Samarium Concentration and Optical Correlation of Tellurite Glass
Modifying the structural and optical properties of inorganic glasses via controlled doping of various rare earth ions by inhibiting the quenching effect is a challenging task. We report the influence of samarium (Sm3+) ions concentration on enhanced optical properties of tellurite glass. A series of...
