제목 | Design and Discovery of Novel Long Wavelength Emission Phosphors |
초록 | Typical white LEDs composed of blue light excitable green-, yellow-, and red-emission phosphors and blue LED chip. As a red-emission phosphor, Eu2+-activated nitrides or Mn4+-doped fluoride phosphors have been mainly used, however, these phosphors require special furnace or atmosphere to synthesize a single phase materials. The development of novel red-emission phosphors, which can be easily synthesized in normal processing, is extremely important in white LEDs application. In addition, blue light excitable long wavelength emission phosphors have been recently investigated as a spectral converter to enhance the energy conversion efficiency of silicon solar cells. Therefore, the investigations have been devoted to search for novel approach to develop novel long wavelength emission phosphor for use in white LEDs and silicon solar cells as a spectral converter. In this study, we proposed the further approach to develop novel long wavelength emission phosphors and report the luminescence properties of the novel phosphor developed using further approach. This work was supported by the faculty research fund of Sejong University in 2016. |
