摘要： The present disclosure relates to down-shifting nanophosphors, a method for preparing the same, and a luminescent solar concentrator (LSC) using the same. The down-shifting nanophosphors according to an embodiment of the present disclosure include a core including NaYF4 nanocrystals doped with neodymium (Nd) and ytterbium (Yb), and further include a neodymium (Nd)-doped crystalline shell surrounding the core, or further include a NaYF4 crystalline shell surrounding the crystalline shell. Therefore, the down-shifting nanophosphors efficiently absorb near infrared rays with a wavelength range of 700-900 nm and efficiently emit near infrared rays with a wavelength range of 950-1050 nm. In addition, the down-shifting nanophosphors according to an embodiment of the present disclosure has a size of 60 nm or less, and thus can be applied to manufacture transparent LSC films with ease and can realize transparent solar cell modules having high near infrared ray shifting efficiency.

摘要： A transparent planar heating film includes metal nanoparticles that are disposed on at least a portion of a transparent adhesive film; and a transparent electrode that is completely covered by the transparent adhesive film and has a conductive surface that is laminated to and in direct contact with the metal nanoparticles via the transparent adhesive film. The heating temperature of the transparent planar heating film is a maximum of at least two times higher at the same power consumption than that of conventional planar heating films. Both the transparent adhesive film and the transparent electrode may be flexible so that the transparent planar heating film is flexible. In the transparent planar heating film, the metal nanoparticles may be bonded to desired locations on the conductive surface of the transparent electrode enabling selective heating.

摘要： A method for surface planarization of an object using a light source of a specific wavelength according to an embodiment includes: providing an object in a main chamber; injecting an etching gas into the main chamber; inputting the light source of a specific wavelength onto a surface of the object; and controlling a temperature of the object. According to the method, it is possible to minimize the side effects such as scratches or contamination of the sample that occur in a conventional chemical-mechanical planarization process. In addition, it is possible to allow precise planarization in nanometers (nm) and simultaneously perform planarization to a side surface of a device as well as a large-sized surface, thereby reducing cost and time required for the planarization process. Moreover, since the surface roughness and the electrical conductivity are improved, it is possible to increase the efficiency and output of the LED device.

摘要： A plasmonic structure having an identifier pattern indicating a genuine product for preventing counterfeiting, falsification or reuse, includes a metal layer; a photoconversion pattern layer including a plurality of photoconverting nanoparticles disposed in a pattern on and in direct contact with the metal layer; a metal pattern layer including a plurality of metal particles disposed in a pattern on and in direct contact with the photoconversion pattern layer; and an adhesive film disposed on the metal pattern layer. An identifier pattern indicating a genuine product is easily identified even by visual inspection after irradiation with infrared light irradiation. The plasmonic structure is fundamentally impossible to re-assemble after deformation of the plasmonic structure caused by disassembly of a product or packaging container, thereby preventing counterfeiting, falsification or reuse.

摘要： The present disclosure relates to a transparent luminescent solar concentrator (LSC). The LSC according to an embodiment of the present disclosure includes a polymer resin panel uniformly doped with phosphors. Accordingly, it is possible to greatly improve the transmittance and optical haze compared to the existing LSC manufactured by physically mixing or coating phosphors on the front side of the panel. In addition, it is possible to greatly improve the light collection efficiency of the LSC through the arrangement structure of the solar cells embedded in the polymer resin panel. The polymer resin panel according to an embodiment may be manufactured with flexibility or rigidity according to the purpose of use, and thus can be widely applied to curved structures, for example, building windows, automobile glasses and greenhouse roofs.
