Abstract

Abstract: Thin CdWO4 films were produced on various substrates by pulsed laser deposition. A method of producing transparent films of high structural and optical quality on MgO substrate was developed. It is based on deposition of an amorphous film from a non-stoichiometric CdWO4 –CdO target and a consequent crystallization of the film in oxygen atmosphere at 750 °C. The quality of the films produced was verified by x-ray diffraction, electron probe microanalysis, scanning electron microscopy, Raman and optical spectroscopy. Graphical abstract: Highlights: Thin CdWO4 films were produced on various substrates by pulsed laser deposition. A method of producing transparent films on MgO substrate was developed. It is based on deposition at RT and annealing of the film at 750 °C. Non-stoichiometric CdWO4 –CdO target was used.
