Abstract(in English) In this study, CuBr1-xIx (CuBrI) thin films, which are transparent p-type semiconductors, were deposited on glass substrates by spin coating method. The samples were characterized by transmission spectra, Electron probe micro analysis (EPMA), X-ray diffraction (XRD) and Photoluminescence (PL). The transmission spectra showed that the transmittance was about 80%. EPMA results showed that the bromine in the film did not increase but the iodine increased. The PL results show that the exciton luminescence is enhanced by immersion in the solution, while the luminescence originating from defects is weakened.
