Abstract:

The reversible thermochromic materials, Fe3+-doped Sm3Ga5O12, was prepared via high temperature solid state reaction method, and their structure and properties were characterized by X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FTIR), Raman spectroscopy, scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS) and UV-Vis spectroscopy. With the increase of Fe3+ doping, the samples’ color gradually changed from bright yellow-green to dark green at room temperature, and when the temperature was increased from room temperature to 500 ℃, the color of the samples gradually turned to orange and brown. The yellow-green color of the sample at room temperature is due to its absorption in the violet region and orange-red region, and continuous red shift of absorption edge is accompanied by changes in color with temperature increasing.

Key words: Fe3+-doped Sm3Ga5O12, Color tuning, Thermochromism
