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 (2H11/2yields4I15/2) and 552 nm (4S3/2yields4I15/2), and red emission at 665 nm (4F9/2yields4I 15/2) were observed.In addition to these emission bands, 497 nm emission assigned to the 4F7/2yields4I 15/2 transition was observed. The spectral properties are analyzed from the view points of low phonon energy property and high refractive index.
