Цитата:
A blue-emitting phosphor must be combined with green and red phosphors to create white light when UV or near ultraviolet (NUV) LED is used. Although a large number of oxide-based phosphors emit an intense blue color under UV or NUV light excitation, the high thermal quenching or thermal degradation is a serious problem if they are used in
white LEDs (e.g., BaMgAl10O17:Eu2+ [44]). Ce3+ - or Eu 2+ -activated oxynitride blue phosphors undergo little thermal degradation and have strong absorption of UV or NUV light, enabling them to be alternative candidates for white LEDs. In the following, three types of blue-emitting oxynitride phosphor (i.e., LaAl(Si6zAlz)N10zOz:Ce3+, a-sialon:Ce3+, and (Y,La)-Si–O–N:Ce3+) will be described.
