英文摘要	Ho2O3-doped transparent tellurite glass-ceramics containing a metastable cubic crystalline phase were prepared. The structure, mechanical properties, 2-mm fluorescence, and decay times of the glass and glass-ceramics were investigated. The Judd-Ofelt intensity parameters, spontaneous radiative probability, and absorption and stimulated-emission cross-sections were calculated. After crystallization, the tellurium coordination number increased (3/3 + 1 -> 4), which indicates that the structure changed substantially. The density, refractive index, and Knoop hardness of the glass-ceramics were enhanced compared with those of the precursor glass. After heat treatment, the spontaneous radiative probability and maximum stimulated emission cross-section increased to 172.24 s(-1) and 0.744 x 10(-20) cm(2), respectively. Moreover, the 2-mu m emission intensity of the glasseceramic increased threefold under excitation by a 640-nm laser diode. The lifetime of the Ho3+:I-5(7) level in the transparent glasseceramic was longer than that of precursor glass. The split in the absorption and emission bands and the reduction of the Omega(2) parameter for the glasseceramic confirmed the incorporation of Ho3+ ions into the crystalline phase. The results indicate that TeO2-based glass-ceramics are a promising candidate material for 2-mu m lasers. (C) 2015 Elsevier B.V. All rights reserved.
