Effects of Preparation Conditions in the Spray Pyrolysis on the Characteristics of Ca8Mg(SiO4)4Cl2:Eu2+ Phosphor

Abstract

In spray pyrolysis, the effects of the preparation temperature, flow rate of the carrier gas and concentration of the spray solution on characteristics such as the morphology, size, and emission intensity of Ca 8 Mg(SiO 4 ) 4 Cl 2 :Eu 2 +phosphor powders under long-wavelength ultraviolet light were investigated. The phosphor powders obtained post-treatment had a range of micron sizes with regular morphologies. However, the composition, crystal structure and photoluminescence intensity of the phosphor powders were affected by the preparation conditions of the precursor powders. The Ca
