Bi3+ doped LaGaO3 powders and thin films were prepared by citric acid sol-gel combustion method and pulsed laser deposition (PLD) technique. The highest photoluminescence (PL) and cathodoluminescence (CL) emissions were observed from La1-x GaO3:Bi3+ powders annealed at the appropriate temperature.
Bi3+ doped LaGaO3 powders and thin films were grown via citric acid sol-gel combustion method and pulsed laser deposition (PLD) technique, respectively. X-ray diffraction data confirmed crystallization of the orthorhombic LaGaO3 phase. Inductive coupled plasma spectroscopy data indicated that some Bi3+ ions evaporated at temperatures exceeding 800 degrees C during thermal treatment. The highest photoluminescence (PL) and cathodoluminescence (CL) emissions with a peak stabilized at 370 nm were observed from La1-x GaO3:Bi3+ powders annealed at 1200 degrees C. The PL and CL emission spectra of La1-x GaO3:Bi3+ to those of the powder samples. The effect of Bi3+ concentration and annealing temperature on the properties of powders and thin films is discussed.
