Summary:Results on the characterization of photoluminescent ...-based films, prepared from a sol-gel precursor and heat treated at 700...C, are reported for the first time. The samples showed two emission bands at 554 and 800 nm when excited with a 488 nm Ar-ion laser. The photoluminescent emission measured at room temperature in thin films was attributed to complex vacancy clusters. The films consisted of ... with traces of TiO..., CuO, and CaTiO... and showed porous structures with an average particle size of 50 nm under atomic force microscopy resolution.
