Nitride and oxynitride cerium-based fluorescent materials for solid state lighting |
| abstract |
Three novel cerium (Ce) -based phosphors based on nitrides and oxynitrides emit photons from yellow or blue to green upon excitation by infrared (UV) or blue light. The two yellow luminescent compounds belong to a quaternary Ca-Al-Si-N system with a distinct structure. These high-definition yellow phosphors include ultraviolet (UV) LEDs having three phosphors, such as blue light emitting devices (LEDs) and yellow phosphors, blue LEDs and green-orange phosphors, or red, blue, and green (RGB) phosphors. By combining it can be used for white light illumination. High-definition blue-green phosphor, which can be represented as Sr 2 SiO 4 -δ N δ , can be used to set up UV LEDs and 3 RGB phosphors. |
