摘要：

A reddish orange emission Sr2P2O7:Sm3+ phosphor is prepared by the solid-state reaction method in air, and the crystal structure and luminescence properties of phosphors are investigated. Sr2P2O7:Sm3+ phosphor shows Commission International de I'Eclairage (CIE) chromaticity coordinates (x=0.5753, y=0.4147). White light-emitting diodes (W-LEDs) fabricated using Sr2P2O7:Sm3+ phosphor etc. show CIE chromaticity coordinates (x=0.3471, y=0.3124). These results indicate that Sr2P2O7:Sm3+ phosphor could be a potential suitable reddish orange emitting phosphor candidate for W-LEDs with excitation of a similar to 400nm n-UV LED chip.
