The dependence of luminescence intensity on Sm\(^{3 + }\) ions concentration in alkali borotellurite (ABTe) glasses has been studied. The quenching of luminescence intensity happens around 0.75 mol% concentration of Sm\(^{3 + }\) ions and it can relate the energy transfer process through cross--relaxation (CR), the CR channels in ABTe: Sm\(^{3 + }\) have been shown. The method of Van Uitert was used to find the dominant interaction mechanism for energy transfer process.
