Abstract

Glasses containing Er³⁺ ions of 0.3 to 7 cation mol percent were prepared in the system of Ga₂S₃-GeS₂-LaS ₃. Frequency upconversion spectra of Er³⁺ in the glasses were measured under the excitation at 800 nm and 980 nm. Green emissions at 533 nm (²H_11/2yields⁴I_15/2) and 552 nm (⁴S_3/2yields⁴I_15/2), and red emission at 665 nm (⁴F_9/2yields⁴I _15/2) were observed.In addition to these emission bands, 497 nm emission assigned to the ⁴F_7/2yields⁴I _15/2 transition was observed. The spectral properties are analyzed from the view points of low phonon energy property and high refractive index.
