“…Clearly, not only PL intensity increases with erbium content but also does the effective width of the emission band. Additionally, the Δλ eff values for the excitation at 800 nm is higher for these glasses than for the 980 nm excitation [11].…”

“…Such processes are typical of erbium ions which are involved in the formation of clusters [12]. It was established in our previous work [5] that clusters of up to 10 3 erbium ions form in the Ag 0.05 Ga 0.05 Ge 0.95 S 2 -Er 2 S 3 glasses.…”

“…The most commonly used RE is erbium that has an intensive emission band near 1.5 μm and low energy losses in fiber optics at this wavelength. Additionally, erbiumdoped crystalline and amorphous materials can be used as active media in laser technology [1], displays, optical amplifiers, photonic devices [2], non-contact temperature [3,4] and g-irradiation sensors [5,6,7].…”

“…An In our previous works on these glasses, we investigated the main structural units of the glass-forming matrix by Raman spectroscopy, as well as photoluminescence spectra under excitation by 532 and 980 nm wavelengths [4,9]. Partial clustering of erbium ions was established from EPR and static magnetization studies, and the effect of g-irradiation on glass photoluminescence was analyzed [5].…”

Absorption spectra of the glasses Ag28Ga28Ge532Er2S1123 and Ag12Ga12Ge228Er2S483 in the 450-1050 nm range at room temperature were investigated. PL bands with maxima at 980 and 1540 nm were recorded under laser excitation with 800 nm wavelength. PL emission mechanism is analyzed from energy transfer processes, taking into account partial cluster formation of erbium ions and energy transition diagram of Er3+.

“…This is because erbium ions in glasses may occupy several positions, and each may provide photoluminescent radiation. Also, γ-irradiation of the glasses [17] changes the mechanism of the luminescence emission. Whereas, no significant changes in the luminescence spectra were found after γ-irradiation of the (Ga 54.59 In 44.66 Er 0.75 ) 2 S 300 single crystal, which determines its advantage in radiation resistance for the possible applications in optoelectronics.…”
