Application to Temperature Sensor Based on Green Up-conversion of Er3+ Doped Silicate Glass

Abstract

The green up-conversion emissions centered at the wavelengths of about 534nm and 549nm of the Er3+ doped silicate glass were recorded, using a 978 nm semiconductor laser diode (LD) as an excitation source. The fluorescence intensity ratio (FIR) of the green up-conversion emissions at about 534nm and 549nm in the Er3+ doped silicate glass was studied as a function of temperature over the temperature range of 296K-673K. The maximum sensitivity and the temperature resolution derived from the FIR of the green up-conversion emissions are approximately 0.0023K-1 and 0.8K, respectively. It is demonstrated that the prototype optical temperature sensor based on the FIR technique from the green up-conversion emissions in the Er3+ doped silicate glass could play a major role in temperature measurement.

Structural, morphological and luminescence properties of nanocrystalline up-converting Y1.89Yb0.1Er0.01O3 phosphor particles synthesized through aerosol route

“…In recent years, there is a great interest in the investigation of up-conversion luminescence materials due to the wide range of their applications, such as in solid state lasers, screen displays, sensors, optical data storage, fluorescent labels for sensitive detection of bio-molecules and telecommunications [2][3][4][5][6]. The most commonly used activator is trivalent rare earth ion Er 3+ since it posses the metastable 4 I 9/2 and 4 I 11/2 levels that can be filled using the low-cost high-power diode laser of 980 nm.…”
