Abstract

ZnGa₂O₄:Mn phosphor particles of spherical shape, clean surface, filled morphology, and improved photoluminescence characteristics were prepared by a modified spray pyrolysis technique and the effect of precursor type on the luminescence intensity of ZnGa₂O₄:Mn was investigated. The morphology control of ZnGa₂O₄:Mn phosphor particles in spray pyrolysis was attempted by using the stable colloidal solution obtained by the liquid phase reaction method as a spraying solution. The ZnGa₂O₄:Mn particles prepared from the colloidal solution had a spherical shape, clean surface, and filled morphology even after post-treatment at 1200°C. The ZnGa₂O₄:Mn particles prepared from Zn chloride and Mn acetate showed the maximum photoluminescence intensity, which was 24% higher than that of particles prepared from Zn nitrate and Mn nitrate.
