Abstract

The optical heating of upconverting particles and its surrounding volume has a vital role in biomedical and therapeutic applications. The internal self-heating in (Y0.968 Er0.002 Yb0.030)2O3 upconverting particles synthesized by urea assisted combustion route has been detected under 980 nm diode laser excitation. A temperature rise up to 348 K has been computed using fluorescence intensity ratio (FIR) method of the thermalized upconversion emission bands due to 2H11/2→4I15/2 and 4S3/2→4I15/2 transitions of Er 3+ion. The results indicate that the material is an interesting candidate for optical heater in biomedical applications.
