## Abstract A new phosphor, Cd~2~Ge~7~O~16~:Mn^2+^, which emits orangeโcoloured longโlasting phosphorescence upon UV light excitation, was prepared by the conventional highโtemperature solidโstate method and its luminescent properties were systematically investigated. Xโray diffraction, photolumine
4 :Sm 3+ Prepared by Sol-Gel Method. -The title phosphor is synthesized by the sol-gel method starting with an aqueous solutions containing Ca(NO3)2, SnCl4, Sm2O3, HNO3, and citric acid (90 ยฐC, calcination of the obtained gel at 900 ยฐC for 6 h in air). The samples are characterized by XRD, SEM, phot
