    摘要: A solution for designing and/or fabricating a structure including a quantum well and an adjacent barrier is provided. A target band discontinuity between the quantum well and the adjacent barrier is selected to coincide with an activation energy of a dopant for the quantum well and/or barrier. For example, a target valence band discontinuity can be selected such that a dopant energy level of a dopant in the adjacent barrier coincides with a valence energy band edge for the quantum well and/or a ground state energy for free carriers in a valence energy band for the quantum well. The quantum well and the adjacent barrier can be formed such that the actual band discontinuity corresponds to the target band discontinuity.

    摘要: A light emitting heterostructure and/or device in which the light generating structure is contained within a potential well is provided. The potential well is configured to contain electrons, holes, and/or electron and hole pairs within the light generating structure. A phonon engineering approach can be used in which a band structure of the potential well and/or light generating structure is designed to facilitate the emission of polar optical phonons by electrons entering the light generating structure. To this extent, a difference between an energy at a top of the potential well and an energy of a quantum well in the light generating structure can be resonant with an energy of a polar optical phonon in the light generating structure material. The energy of the quantum well can comprise an energy at the top of the quantum well, an electron ground state energy, and/or the like.

    摘要: The invention relates to phosphor-conversion (PC) sources of white light, which are composed of at least two groups of emitters, such as blue electroluminescent light-emitting diodes (LEDs) and wide-band (WB) or narrow-band (NB) phosphors that partially absorb and convert the flux generated by the LEDs to other wavelengths, and to improving the quality of the white light emitted by such light sources. In particular, embodiments of the present invention describe new 3-4 component combinations of peak wavelengths and bandwidths for white PC LEDs with partial conversion. These combinations are used to provide spectral power distributions that enable lighting with a considerable portion of a high number of spectrophotometrically calibrated colors rendered almost indistinguishably from a blackbody radiator or daylight illuminant, and which differ from distributions optimized using standard color-rendering assessment procedures based on a small number of test samples.

    摘要: The current invention discloses polychromatic sources of white light, which are composed of at least two groups of colored emitters, such as light-emitting diodes (LEDs) are disclosed. Based on a novel approach of the assessment of quality of white light using 1269 test color samples from the enhanced Munsell palette, the spectral compositions of white light composed of two to five (or more) narrow-band emissions with the highest number of colors relevant to human vision rendered almost indistinguishably from a blackbody radiator are introduced. An embodiment of the current invention can be used, in particular, for designing polychromatic sources of white light with the ultimate quality capable of rendering of all colors of the real world.

    摘要: An improved nitride-based light emitting heterostructure is provided. The nitride-based light emitting heterostructure includes an electron supply layer and a hole supply layer with a light generating structure disposed there between. The light generating structure includes a set of barrier layers, each of which has a graded composition and a set of quantum wells, each of which adjoins at least one barrier layer. Additional features, such as a thickness of each quantum well, can be selected/incorporated into the heterostructure to improve one or more of its characteristics. Further, one or more additional layers that include a graded composition can be included in the heterostructure outside of the light generating structure. The graded composition layer(s) cause electrons to lose energy prior to entering a quantum well in the light generating structure, which enables the electrons to recombine with holes more efficiently in the quantum well.
