【 摘 要 】

Orange-red phosphors NaY(WO4)2:Eu3+, Sm3+were successfully synthesised by hydrothermal synthesis method. The photoluminescence (PL) properties were investigated. The PL emission spectrum of Na Y (WO4)2: Eu3+shows good luminous properties under 398 nm, which mainly located at 596 and 615 nm, with the additional of Sm3+could broaden and increase emission intensity of Eu3+, which could be suitable for the excitation of UV light emitting diodes (LEDs) (∼400 nm). The PL results indicated that Na Y (WO4)2: Eu3+, Sm3+may be a promising red phosphor candidate for use in white LEDs.
