Abstract:
Certain example embodiments relate to a burner for use in combustion deposition depositing a coating on a substrate. An infrared (IR) burner generates radiant energy in an area between the burner and the substrate. A delivery device (1) provides a stream comprising a substantially vaporized precursor and a carrier gas from a location remote from the radiant energy generated by the IR burner, and (2) causes the stream to flow between the substrate and the IR burner. The stream is substantially laminar when exiting the delivery device. The radiant energy is sufficient to cause the precursor in the stream to be combusted and to heat the substrate to allow at least a portion of the combusted precursor to form the coating, directly or indirectly, on the substrate. The burners of certain example embodiments may be used, for example, to combustion deposition deposit metal oxide coatings onto glass substrates.
Abstract:
Certain example embodiments of this invention relate to heatable glass substrates that may be used in connection with lighting applications, and/or methods of making the same. In certain example embodiments, a glass substrate supports an antireflective (AR) coating on a first major surface thereof, and a conductive coating on a second, opposite major surface thereof. Bus bars connect the conductive coating to a power source in certain example embodiments. The substrate may be heat treated (e.g., heat strengthened and/or thermally tempered), with one or both coatings thereon. The heatable glass substrate thus may help provide a chemical and/or environmental barrier for the luminaire or lighting system disposed behind it. In addition, or in the alternative, the heatable glass substrate may help reduce the amount of moisture (e.g., snow, rain, ice, fog, etc.) that otherwise could accumulate on the luminaire or lighting system.
Abstract:
Certain example embodiments relate to a burner for use in combustion deposition depositing a coating on a substrate. First and second spaced-apart combustion gas manifolds are configured to respectively produce first and second flames (which may effectively combine to form a single flame front beyond the outer face of the burner in certain example embodiments). The first and second combustion gas manifolds form a precursor reaction zone therebetween. An adjustable precursor delivery manifold located between the first and second combustion gas manifolds is configured to receive a precursor used in forming the coating. The precursor delivery manifold is positioned so as to substantially directly provide the precursor to a desired or predetermined portion of the precursor reaction zone. The precursor delivery manifold includes first and second cooled walls arranged to reduce the occurrence of precursor pre-reactions upstream of the precursor reaction zone. The burners of certain example embodiments may be used to combustion deposition deposit metal oxide coatings onto glass substrates.
Abstract:
Certain example embodiments relate to systems and/or methods for preferentially and selectively heat treating conductive coatings such as ITO using specifically tuned near infrared-short wave infrared (NIR-SWIR) radiation. In certain example embodiments, the coating is preferentially heated, thereby improving its properties while at the underlying substrate is kept at low temperatures. Such techniques are advantageous for applications on glass and/or other substrates, e.g., where elevated substrate temperatures can lead to stress changes that adversely effect downstream processing (such as, for example, cutting, grinding, etc.) and may sometimes even result in substrate breakage or deformation. Selective heating of the coating may in certain example embodiments be obtained by using IR emitters with peak outputs over spectral wavelengths where the conductive coating (or the conductive layer(s) in the conductive coating) is significantly absorbing but where the substrate has reduced or minimal absorption.
Abstract:
Certain example embodiments of this invention relate to articles including anticondensation and/or low-E coatings that are exposed to an external environment, and/or methods of making the same. In certain example embodiments, the anticondensation and/or low-E coatings may be survivable in an outside environment. The coatings also may have a sufficiently low sheet resistance and hemispherical emissivity such that the glass surface is more likely to retain heat from the interior area, thereby reducing (and sometimes completely eliminating) the presence condensation thereon. The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator/freezer doors, and/or the like.

Abstract:
Certain example embodiments relate to the deposition of metal oxide coatings via combustion deposition. In certain example embodiments, the metal oxide coating may be a silicon oxide coating (e.g., SiO2, or other suitable stoichiometry) and, in certain example embodiments, the silicon oxide coating may serve as an anti-reflective (AR) coating. In certain example embodiments, a percent visible transmission gain of at least about 2.0%, and more preferably between about 3.0-3.25%, may be realized through the growth of films on a first surface of the substrate. The coatings produced in accordance with certain example embodiments possess an enhanced transmission increase over previously combustion deposition produced single-layer anti-reflective coatings. This may be accomplished in certain example embodiments by provided mixed or graded microstructure metal oxide coatings (e.g., silicon oxide growths that alternate between using process conditions that produce small nucleation particle size distributions and process conditions that produce large agglomerate nano-particle size distributions) and/or by in situ nano-particle matrix loading of metal oxide coatings via combustion deposition.
