摘要：
The internal optical heating in the cubic phase Er3+-Yb3+ and Eu3+-Er3+-Yb3+ codoped Y2O3 phosphors synthesized by low temperature, urea assisted combustion technique due to near infrared (NIR) diode laser excitation have been performed by monitoring the upconversion luminescence bands corresponding to the H-2(11/2) -> I-4(15/2) and S-4(3/2) -> I-4(15/2) transitions of Er3+ ions. The results indicate that the developed phosphor materials are of significant interest for making optical heater. (C) 2013 Elsevier B.V. All rights reserved.
