摘要:

采用传统高温固相法合成了系列Fe掺杂钐镓石榴石Sm3Ga5-xFexO12(x=1,2,3,4)可逆热致变色材料, 并通过粉末X射线衍射(XRD)、 红外光谱(FTIR)、 拉曼光谱(Raman)、 扫描电子显微镜(SEM)、 X射线光电子能谱(XPS)及固体紫外光谱分析技术研究了物质的结构及性质. 在室温下, 随着铁掺杂量的增加, 样品的颜色从亮黄绿色逐渐变为深墨绿色, 且随着温度从室温升至500 ℃, 样品的颜色也逐渐变为相应的橘黄色和棕色. 样品在室温下所呈现的黄绿色是源于其在紫色光区域及橙红色光区域内有相应的吸收行为, 且随着温度的升高, 吸收行为持续红移, 样品颜色也随之发生变化.

关键词: 铁掺杂钐镓石榴石, 颜色调控, 热致变色

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
