Abstract

Enhancement both in up-conversion violet emission at 399 nm (⁴D_3/2 → ⁴I_13/2 or ²P_3/2 → I_11/2) and in absorption strength has been observed from Nd³⁺ doped SiO₂-Al₂O₃ sol-gel glasses after the addition of co-dopant (Ce³⁺) ions in different contents (0.01 to 1 mol%). A very intense violet up-conversion emission was measured at an optimum Ce³⁺ co-doping concentration of 0.05 mol%, when the neodymium sol-gel glass was excited with a yellow light at 577 nm(⁴I_9/2 → ⁴G_5/2).
