摘要: Europium doped yttrium oxide submicron-sized particles were prepared by ultrasonic aerosol pyrolysis. To examine the size effect of submicron-sized-particle, photoluminescence was investigated. The particle controlled pH, reaction temperature, molar concentration in precursor solution. PL intensity decreased with size. When is above about 150 times Bohr radius YO, optical property shows bulk characteristics.
