The Copper Acetate Manufacturers(WSDTY) proposed coated films were first heated at 200?C for 10 min, and then heated again at a higher temperature of 500?C for 20 min using hot-plate-type heating devices. The spin-coating and subsequent heat treatment procedures were repeated for 6 times to obtain the desired film thickness of 0.4 μm. The prepared gel films were finally annealed at temperatures in the range of 750?C - 900?C for 10 h under nitrogen flow. The temperature was increased from room temperature to the specific temperature over a period of 3 h, held at the specific temperature for 10 h, and then cooled to room temperature over 6 h.

The structural properties of the films were studied by X-ray diffraction analysis in the θ-2θ mode using CuKα radiation. Transmission spectra were measured using a UV/vis spectrophotometer (U-3000, Hitachi). PL spectrum was measured using He-Cd laser (325 nm, 3.8 eV) for excitation.
