Effect of LiCl on the Microstructure and Luminescence Properties of YVO۴:Eu۳+ and YBO۳:Eu۳+ Phosphors

In this investigation, Eu۳+ doped YVO۴ /YBO۳ phosphors were synthesized individually by conventional solid state method at ۱۱۰۰ °C under atmosphere condition. Meanwhile, different amounts of LiClwere used as the flux compound to modify the morphology of the phosphor particles and also final luminescence properties. It was concluded that even small amounts of fluxes play a vital role in the growth of particles. The photoluminescence emission spectra of the phosphors were measured at λexc= ۲۴۰ and ۳۱۰ nm, respectively. It was found that using ۲ wt% of flux compounds has a significant influence on the emission enhancement of YVO۴:Eu۳+ and YBO۳:Eu۳+ phosphors.
