摘要：

The effects of melt composition on the transmittance of single-crystalline KNbO3 films grown on SrTiO3 substrates by liquid phase epitaxy (LPE) technique were investigated. The growth morphology and transmittance of the KNbO3 films strongly depended on the extra K2CO3 self-flux content in K2CO3 (K2O)-Nb2O5 system. With increasing K2CO3 content close to the eutectic composition (approximate to66 mol%) in the phase diagram, the transmittance of KNbO3 film/SrTiO3 substrate increased up to 70% in the visible wavelength range. Atomic force microscopy (AFM) clearly showed that the parallel flat steps formed toward the dipping direction and their interval decreased with increasing the K2CO3 content.
