The fluorescence and up-conversion spectral properties of Er3+-doped TeO2-ZnO and TeO2-ZnO-PbCl2 glasses suitable for developing optical fiber amplifier and laser have been fabricate and characterized. Strong green (around 527-550 nm) and red (around 661 nm) up-conversion emissions under 977 nm laser diode excitation were investigated, corresponding to 2H11/2, 4S3/2, ® 4I15/2 and 4F9/2 ® 4I15/2 transitions of Er3+ ions respectively, have beenobserved and the involved mechanisms have been explained. The dependence of up-converted fluorescence intensity versus laser power confirm that two-photons contribute to up-conversion of the green-red emissions. The novelty of this kind of optical material has been its ability in resisting devitrification, and its promising optical properties strongly encourage for their further development as the rare-earth doped optical fiber amplifiers and upconversion fiber laser systems.

Dy3+-doped GeSe2–Ga2Se3–CsI chalcohalide glasses were prepared. The thermal stabilities, optical properties, emission properties, and structure of the glasses were investigated. Upon excitation with a 808-nm diode laser, 1.32-μm near-infrared fluorescence was observed with a broad full width at half-maximum of about 90 nm. It was found the 1.32-μm fluorescence lifetime of the Dy3+-doped GeSe2–Ga2Se3–CsI glass depends on the I/Ga molar ratio and the amount of Ga2Se3 and CsI. The longest lifetime is >2.5 ms. It is noted that the value is significantly higher than those in other Dy3+-doped glasses. The enhancement of lifetime can be attributed to a decreased local phonon mode, which dominates the multiphonon relaxation. Meanwhile, it is interesting to note that the GeSe2–Ga2Se3–CsI glasses have shown good infrared transmittance. As a result, Dy3+-doped GeSe2–Ga2Se3–CsI glasses have been considered to be an attractive host for a 1.3-μm optical fiber amplifier.
