Fluoindinate glass (FIG) is considered an ideal material for fiber laser devices and mid-infrared bulk optics components owing to its ultra-low phonon energy and broad transparency window. However, the heat generated by devices fabricated with FIG during their operation limits its application. Therefore, there is an urgent need to study its high-temperature properties. In this study, the thermal properties, microstructure, crystal phase behaviors, and optical and luminescent properties of high-temperature FIG were comprehensively evaluated. We also attempted to reveal the changes in its structure at high temperatures using variable-temperature Raman spectroscopy. We first found that the stretching vibration intensity of nonbridging F(F nb ) decreases, and the bending vibration of FIG increases with an increase in temperature, indicating that high temperatures could lead to the fracture of bridge bonds between some [InF 6 ] 3− octahedrons. Certainly, this will lead to glass structural instability, which will further increase the tendency of FIG to undergo devitrification in high-temperature conditions. We believe that this work will provide a reference for the performance improvement and application of fluoride glass at high temperatures.

In the current study, a cost‐effective simple strategy has been developed for the surface modification of ZnO nanorods (NRs). The ZnO NRs were surface modified using stearic acid. The ZnO NRs and stearic modified ZnO NRs were characterized using various analytical techniques. FT‐IR, TGA, and CHO analyses prove successful surface modification of ZnO NRs with stearic acid. FE‐SEM and TEM analyses show no change in morphology of ZnO NRs before and after the surface modification. The stearic acid modified ZnO NRs show water contact angle greater than 90° which suggests their hydrophobic nature. XPS analysis shows presence of Zn2+ and O2− in pure ZnO and the stearic acid modified ZnO NRs. The stearic acid modified ZnO NRs were explored for self‐cleaning and they were also tested as catalyst for photocatalytic degradation of crystal violet in an aqueous solution. Kinetics and recyclability studies were also carried out for the photodegradation of crystal violet using the stearic acid modified ZnO NRs.
