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： The present invention relates to a novel method for preparing a water-insoluble metal hydroxide, and a use thereof. The water-insoluble metal hydroxide of the present invention is conveniently and efficiently prepared s through the high-temperature heat treatment step two times and the washing step, and thus contains a small amount of an alkali metal and has a high crystallinity and a phase purity. The water-insoluble metal hydroxide of the present invention or metal oxide therefrom exhibits an absorption wavelength at a low wavelength range (for example, 490 nm or less) and a light emitting wavelength at a high wavelength range (for example, from 500 nm or more to less than 1,100 nm). Accordingly, the water-insoluble metal hydroxide of the present invention may be efficiently used in various applications such as a fire retardant, an antacid, an adsorbent and so forth, and may also be doped with another metal ion to be utilized as a raw material for fabricating a catalyst, a fluorescent material, an electrode material, a secondary battery material and the like.

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.
