Crystalline β-BBO thin films were successfully prepared on (001)-oriented Sr 2+-doped α-BBO substrates by using liquid phase epitaxy, pulsed laser deposition and vapor transport equilibration techniques. The films were characterized by X-ray diffraction and X-ray rocking curve. The present results manifest that the β-BBO thin films grown on Sr 2+-doped α-BBO substrates have larger degree of orientation f value and smaller X-ray rocking curve FWHM than the ones grown on other reported substrates.
