Abstract

The europium doped yttrium oxide (Y2O3:Eu3+) thin film was formed on a Si substrate by the conventional spin-coating process followed by rapid thermal annealing (RTA) treatment. The spinning profiles such as rotation speed, acceleration and holding times were controlled during the spin-coating process for the best condition of the Y2O3:Eu3+ thin film. The RTA treatment was conducted for several temperature in order to crystallize the spin coated film. The Y2O3:Eu3+ thin film presented best performance in the conditions of 4000 rpm, 30 s and 10 s of rotation speed, acceleration time and holding time, respectively, at a fixed RTA temperature of 900 ℃.
