摘要：

Cr4+-doped transparent beta-Zn2SiO4 glass-ceramics were prepared by heat treatment on the as-made glasses. It was confirmed from the absorption spectra that Cr4+-doped beta-Zn2SiO4 glass-ceramics are indeed a low-field system. The broadband infrared emission centering at 1342 nm with the full width at half-maximum of more than 285 nm was observed by exciting the glass-ceramics with the excitation of an 808 nm laser diode. The observed infrared emission could be attributed to Cr4+ ions at low-field sites in beta-Zn2SiO4 glass-ceramics. (C) 2010 Optical Society of America
