Abstract

Abstract: In this work, Pr 3+ ion‐doped Ge20 Ga15− x Sb x Se65 ( x = 0, 5, 10, in mol%), Ge20 Sb15− y In y Se65 ( y = 5, 10, in mol%), Ge20 Ga15− z In z Se65 ( z = 0, 5, 10, in mol%), and Ge20 Ga5 Sb10 Se60 I5 glasses were prepared. The structural units, thermal properties, and optical properties of these glasses were analyzed. In addition, a comprehensive comparison study of the effects of metal ions (Sb, Ga, and In), S/Se ratio, and I content on the mid‐infrared (MIR) luminescence of Pr 3+ ions was conducted. Under a 1.55‐μm laser pump, 0.2 mol% of Pr 3+ ion‐doped chalcogenide glasses performed strong photoluminescence in the wavelength range of 3.5‐5.5 μm. Results indicated that the Sb‐containing glass performed the strongest emission intensity among the studied glasses. Moreover, halogen element I can reduce the phonon energy of the matrix, which is beneficial to the luminescence of Pr 3+ ions and provide significant possibilities for developing MIR lasers and amplifiers.
