In this work, CaMgSi2O6:Eu2+nanoparticles were synthesized by co-precipitation method with different volume ratio of water and ethanol as a solvent mixture. These synthesized nanoparticles were calcinied at different temperatures. We observed CaMgSi2O6:Eu2+ particles obtained from volume ratio of W: E as 0:1 and calcinied at 1000 OC for 2 hrs gave uniform particle size and high photoluminescence intensity. The dielectric constant of solvent depends upon volume ratio of solvent mixture which is responsible for electrostatic interaction and nucleation rate of particles. The synthesized blue phosphor shows absorption band in UV range with emission at 478 nm.
