以H3BO3助熔剂采用高温固相反应法制备了LiMo2O8∶Eu3+红色荧光粉。通过XRD、SEM及激发和发射光谱对样品进行了研究,结果表明,引入助熔剂为3 wt%时样品具有好的结晶和优良的光谱性质;光谱测量的结果表明,在近紫外、蓝光激发下,能发射出615nm的红光,具有较高的色纯度。因此,可作为目前已商品化的白光LED的红色补偿荧光粉,也可作为近紫外LED和三基色荧光粉组合型白光器件的红色荧光粉的候选材料。 LiMo2O8:Eu3 + red phosphor was prepared by high-temperature solid-state reaction with H3BO3 flux. The samples were investigated by XRD, SEM and excitation and emission spectroscopy. The results show that the samples with 3 wt% flux have good crystallinity and good spectral properties. The results of spectral measurement show that under near-UV and blue excitation , Can emit 615nm red light, with high color purity. Therefore, it can be used as the red compensating phosphor of white LED which has been commercialized at present, and also as the candidate material of the red phosphor of near white LED and trichromatic phosphor.
