| Summary: | Title screen This work is devoted to the formation of YAG:Ce3+ phosphor coatings using mid-frequency magnetron sputtering of a set of metallic yttrium, aluminum, and cerium targets in an argon-oxygen gas mixture. This method allows for an increase in the deposition rate of the (Y–Al–O):Ce precursor coating by more than an order of magnitude compared to RF reactive magnetron sputtering of ceramic targets. The surface morphology, microstructure, phase and elemental composition, as well as the optical and cathodoluminescent (CL) properties of the synthesized YAG:Ce coatings were studied at different annealing temperatures during high-temperature annealing in air (800–1200 °C) and at different heating/cooling rates (2 and 7 °C/min). The CL spectra demonstrate the presence of radiative transitions in Ce3+ ions. It was found that the CL intensity is significantly higher in samples annealed at a heating rate of 2 °C/min, which correlates with a lower concentration of microdefects and greater phase composition homogeneity of the synthesized coatings. The intensity increases with annealing temperature in the range from 490 to 850 nm. The proposed approach can potentially be used to create luminescent coatings with high emission properties Текстовый файл AM_Agreement |
