The green up-conversion emissions centered at the wavelengths of about 534nmand 549nm of the Er doped silicate glass were recorded, using a 978 nm semiconductorlaser diode (LD) as an excitation source. The fluorescence intensity ratio (FIR) of the greenup-conversion emissions at about 534nm and 549nm in the Er doped silicate glass wasstudied as a function of temperature over the temperature range of 296K-673K. Themaximum sensitivity and the temperature resolution derived from the FIR of the green up-conversion emissions are approximately 0.0023K and 0.8K, respectively. It isdemonstrated that the prototype optical temperature sensor based on the FIR technique fromthe green up-conversion emissions in the Er doped silicate glass could play a major role intemperature measurement.
以978纳米半导体激光二极管(LD)作为激发源,记录了掺铒硅酸盐玻璃在约534纳米和549纳米波长处的绿色上转换发射。研究了掺铒硅酸盐玻璃中约534纳米和549纳米处绿色上转换发射的荧光强度比(FIR)随温度在296K - 673K范围内的变化。由绿色上转换发射的FIR得出的最大灵敏度和温度分辨率分别约为0.0023K和0.8K。结果表明,基于掺铒硅酸盐玻璃中绿色上转换发射的FIR技术的原型光学温度传感器在温度测量中可发挥重要作用。
