Deposition of optical quality C-axis oriented epitaxial thin film of ruby via pulsed laser deposition technique on sapphire substrate is reported. The film is characterized by Raman spectra and photoluminescence spectra. The peak positions of R-line and the corresponding linewidth are observed to be temperature dependent. The sensitivity of R(1)-line position, υ, with the temperature, (dυ/dT), in the range of 138-368 K shows linear behavior confirming its applicability as temperature sensor.
报道了通过脉冲激光沉积技术在蓝宝石衬底上沉积光学质量的C轴取向红宝石外延薄膜。该薄膜通过拉曼光谱和光致发光光谱进行表征。观察到R线的峰值位置和相应的线宽与温度有关。在138 - 368 K范围内，R(1)线位置υ随温度的灵敏度(dυ/dT)呈线性行为，证实了其作为温度传感器的适用性。
