论文摘要
近年来，光敏材料的需求量很大，因为它们具有将吸收的光子能量转化为产生应变的能力，因此对物理性质进行了调整。在本报告中，我们检测到SRMNO3的光敏活动。使用依赖性和温度依赖性的拉曼研究，其不同的激光源在SRMNO3的光节间隙中具有波长，我们泄露了SRMNO3薄膜的光敏特征。在激光照明时，拉曼模式会软化并随着激光功率的增加而进一步增加。在固定激光功率下温度升高时，观察到类似的模式变化。在存在激光照明的情况下，XAS揭示了与模式软化相关的晶体场分裂的变化。
In recent years, photosensitive materials have been in huge demand because of their fascinating ability to convert absorbed photon energy to generate strain and henceforth tuning the physical properties. In this report we detect the photosensitive activity of SrMnO3. Using the power dependent and temperature dependent Raman study with different laser sources having wavelengths across the optical band gap of SrMnO3, we divulge the photosensitive character of SrMnO3 thin films. Upon laser light illumination, Raman modes soften and softening further increases with increase in laser power. Similar kind of mode variation is observed with increasing temperature at fixed laser power. XAS in presence of laser illumination, reveals the change in crystal field splitting associated with mode softening.
