文摘

In this paper, we report a novel phenomenon in GeS₂−In₂S₃−CsI chalcohalide glasses doped with Tm³⁺ ions. Under irradiation with an 808 nm laser diode, a bright red emission centered at 700 nm is observed for the first time. By codoping with different concentration of Er³⁺ ions, emission can be tuned from monochromatic red to green. The Er³⁺ ions codopant and higher concentration of Tm³⁺ ions are favoring the 700 nm red emission. Meanwhile, the indium (In) contents plays a significant role on the enhanced upconversion and near-IR emissions. These observations are interesting and may enable the device based on the chalcohalide glass to meet the specific color demands, which have potential applications in the fields of optical and solid state lasers.
