Abstract: Photoluminescence (PL) of Er3+ ions embedded in GaLaS(O) glass at excitation wavelengths of 488, 532, 660, 808, and 980 nm has been studied. Typical cases at which the ratios of the optical transition intensities have no dependence on the pumping intensity have been considered. For the case of pumping at the 488 nm wavelength the method of extrapolation coefficients, which reveals the up-conversion nature of PL "mimicking" a "normal" PL, has been demonstrated. The thermal coupling of S 3 / 2 4 and H 11 / 2 2 manifolds, which are responsible for the intense PL in the green region of the visible spectral range, is discussed. • Photoluminescence (PL) of erbium doped GaLaS(O) glass at laser excitation of 488, 532, 660, 808, 980 nm is studied. • The method of extrapolation coefficients reveals up-conversion nature of PL mimicking a normal PL. • The thermal coupling of 4S 3/2 and H 11 / 2 2 manifolds has been investigated.
