Description:
A reddish orange emission Sr 2 P 2 O 7 :Sm 3+ phosphor is prepared by the solid-state reaction method in air, and the crystal structure and luminescence properties of phosphors are investigated. Sr 2 P 2 O 7 :Sm 3+ phosphor shows Commission International de I'Eclairage (CIE) chromaticity coordinates (x = 0.5753, y = 0.4147). White light-emitting diodes (W-LEDs) fabricated using Sr 2 P 2 O 7 :Sm 3+ phosphor etc. show CIE chromaticity coordinates (x = 0.3471, y = 0.3124). These results indicate that Sr 2 P 2 O 7 :Sm 3+ phosphor could be a potential suitable reddish orange emitting phosphor candidate for W-LEDs with excitation of a ~400 nm n-UV LED chip.
