Sr2MgB2O6:Eu3+ red phosphor has been synthesized by modified solid-state reaction method. The photoluminescence properties of Sr2MgB2O6:Eu3+ phosphor have been investigated. Sr2MgB2O6:Eu3+ phosphor can be effectively excited by 394 nm and generate red emission at 615 nm. Eu3+ ions occupy both Sr2+-site and Mg2+-site in Sr2MgB2O6. Univalent charge compensators (Li+, Na+ and K+) can obviously improve the photoluminescence properties of Sr2MgB2O6:Eu3+ phosphor and Na+ is the optimal charge compensator. The effect of substitution of M2+ (M = Mg, Ca or Ba) ion for Sr2+ on the photoluminescence properties of Sr2MgB2O6:Eu3+ phosphor has also been discussed. It implies that Sr2MgB2O6:Eu3+ may be a potential red phosphor for near-UV W-LEDs or other display devices.
