关 键 词:Phosphor Rare Earth Luminescent Property White LED
摘 要:正 Several phosphors activated by rare earth ions, which may be used for the conversion of UV light from a LED to white light, have been prepared, and the photoluminescent properties of these phosphors, especially those with the excitation wavelength at 371nm and above, have been studied. Y202S:Eu3+ may be better than Y2O3:Eu3+ and Y(P,V)O4:Eu3+ for using as the red component in white LED. Eu2+ , Mn2+-activated aluminate is much better than Ce3+ , Tb3+ -activated aluminate for us-ing as the green component. Both Eu2+-activated aluminate and halophosphate are good candidates for the blue component.
