Coatings on various substrates (stainless steel, ceramics, YAG crystals), as well as self-standing plates, were obtained. The coatings adhered on materials with large variety of thermal expansion. Besides microstructural, crystallographic, and thermal-stability investigations, optical tests were performed. They included cathodoluminescence (CL), UV-VIS-NIR reflectance, and response on various wave lengths. After spraying, the YAG phase sustained, but an amorphous fraction was present. Coatings were heat-treated to crystallize fully and change their optical properties. Minor amorphous fraction crystallized at 930 °C. The heat-treated coatings exhibited higher CL and also larger emission when illuminated with a 366 nm. The optical responses were influenced by splat boundaries, pores, and thin cracks, which were healed only partly by heat treatment.
