英文摘要	Chalcohalide Ge-In-S and Ge-Ga-S glasses modified by CsX (X = Cl, Br, and I), and doped with Er in the range from 0.1 to 0.5 at.%, have been prepared and investigated. The influence of CsX addition on their optical properties has been studied by transmission and photoluminescence spectroscopy. Nominal compositions of [Ge25In(Ga)(10)S-65](90)(CsX)(10) have been selected as host materials. The shift of the absorption edge as a function of caesium halides is observed in GeInS (CsX) system with maximum band gap observed for CsI. The low-temperature photoluminescence reveals the broad band luminescence of the host glass centered at around the half of the band gap energy with superimposed 4f-4f radiative transitions of Er3+ ions. The position of the broad luminescence band is considerably shifted to higher energy in the case of CsI ascompared to CsCl and CsBr. In the case of Er-doped chalcohalide (Ge25Ga10S65)(90)(CsBr)(10) system, a considerable narrowing of I-4(13/2) -> I-4(15/2) radiative transitions of Er3+ ions accompanied by the pronounced splitting of the emission sub-bands clearly documents the increasing ceramics-like nature in the host material due to the admixture of CsBr. The influence of CsBr concentration on the shape of the broad-band luminescence of Ge-Ga-S-CsBr host is also reported. (C) 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
