“…A considerable number of publications dealing with the properties of fluoride glasses have been published such as ZrF 4 -BaF 2 -LaF 3 -AlF 3 -NaF (ZBLAN) system [5][6], LiF-NaF-ZrF 4 system [7], LnF 3 -(Ln, Zr)-ZrF 4 system (where Ln = Sm, Eu, Tm, Yb) [8], ZrF 4 -NaF-AlF 3 -LaF 3 -SmF 3 -BaF 2 -BaCl 2 system [9] and so on. Yet, only a few studies have been published on GaF 3 /InF 3 based glasses [10][11][12]. So far, to the best of authors' knowledge, there are no studies concerning glasses in the GaF 3 -InF 3 -CdF 2 -ZnF 2 -PbF 2 -SnF 2 -ZrO 2 system.…”

A systematic investigation on glass formation in the 20GaF 3 -15InF 3 -20CdF 2 -15ZnF 2 -(20-x)PbF 2 -10SnF 2 -xZrO 2 (xZ-GICZPS) system (x = 0, 2, 4, 6, 8 in mol.%) was carried out. These glasses were characterized by differential scanning calorimetry (DSC), infrared (IR) spectra and Raman spectra. The DSC results show that the thermal stability is affected by PbF 2 and ZrO 2 contents. With increasing ZrO 2 content, the thermal stability is improved at first and then reduced, which is proved by thermal stability factors ΔT and S determined by DSC. As a result, the 20GaF 3 -15InF 3 -20CdF 2 -15ZnF 2 -14PbF 2 -10SnF 2 -6ZrO 2 glass shows the largest parameters ΔT and S, processing the most excellent thermal stability. Analyses of IR spectra reveal that glasses have broad transparency range in IR region. According to Raman spectra, the glass network structures are basically composed of mixed [(In, Ga)F 6 ] and In[O, F] 6 units and ZrO 2 mainly acts as network modifier in this system.
