## Abstract The radiative and nonradiative transitions of the first three excited levels of Er^3+^ doped in Ga~2~S~3~–GeS~2~–Sb~2~S~3~ glass were investigated. Particularly, we focused on the ^4^I~9/2~ and ^4^I~11/2~ which are the initial and final levels of mid‐infrared emission around 4 µm. The e
