Optical Properties of GGG Epitaxial Films Grown from PbO-B2O3-V2O5 Flux

The paper reports a growth of the high-quality Gd3Ga5O12 (GGG) homoepitaxial films by the liquid phase epitaxy technique using the PbO-B2O3 and PbO-B2O3-V2O5 fluxes.The influence of the flux composition containing V2O5 as well as the growth temperature is discussed basing on the optical absorption and the electron probe micro analysis results.
