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. Compared with other substrates, α-BBO has the similar structure, the same UV cutoff and the same chemical properties to β-BBO. These results reveal that Sr 2+ -doped α-BBO single crystal may be a promising substrate proper to the growth of β-BBO films.
