摘要：
In a given paper, effects of both the magnetron power and the gas ratio of Ar/O-2 on the microstructure and the low-temperature photoluminescence spectra (PL) of the Zn0.9Cd0.1O films are investigated. Single-phase and polycrystalline Zn0.9Cd0.1O films are deposited by direct current magnetron sputtering at a substrate temperature of 250 degrees C. X-ray diffraction (XRD) measurements reveal a strong influence of technological deposition parameters on the films' microstructure. The Williamson-Hall method allows determining the size of coherent-scattering region for all the samples. As revealed, the increase in the argon partial pressure leads to an improvement of crystallinity of ternary solutions, while increasing the power of magnetron causes the deterioration of structure. The features of low-temperature luminescence spectra of the Zn0.9Cd0.1O ternary solutions are discussed in terms of spontaneous fluctuations.
