Blue and red dual emission nanophosphor CaMgSi2O6:Eun+; crystal structure and electronic configuration

► We have synthesized Eu doped CaMgSi2O6 using different volume ratios of water and ethanol solvent. ► We observed Ca2MgSi2O7 phase increases with increasing amount of water in solvent. ► Dual emission was observed using single europium precursor. ► As synthesized material can be used for wavelength conversion application.
