【 摘 要 】

A novel attempt towards the synthesis of red-emitting europium (Eu$^{3+}$)-doped CaSrSiO$_4$ phosphors has been made through a templated strategy using non-ionic surfactant as template. The concentrations of Eu$^{3+}$ in the host were altered and the optimized concentration to extract the maximum efficacy was analysed. The crystalline structure and morphologies ofthe synthesized phosphor were studied and analysed. The results show the aggregated rod-like morphology with a continuous porous network that shows the maximum intensity at 10 mol% of dopant.
