Abstract

Fluorescence intensity ratio (FIR) variation of green upconversion emissions at 523 and 545nm in the Er3+–Yb3+ codoped Al2O3 has been studied as a function of temperature using a 978nm semiconductor laser diode as an excitation source. In the temperature range of 295–973K, the maximum sensitivity an...
