•The phosphor GGG/Ce3+ coating based on silicone resin and potassium liquid glass.•The phosphor GGG/Ce3+ coating have high emission band at 570 nm.•The maximum emission of the coatings at 75 wt.% compound concentration.•Increasing the phosphor concentration results in quenching of the emission bands.
Luminescence and reflectance spectra of coatings based on gadolinium gallium garnet doped by cerium (GGG/Ce3+) with silicone resin or potassium liquid glass compound were analyzed depending on concentration. It was established that the maximum emissions of the coatings at 75 wt.% compound concentration have luminescence band at 570 nm and absorption band at 470 nm. Both bands were detected by absorption or emission of cerium ions in gadolinium gallium garnet. Ce3+ ion transition into Ce4+ ion was observed upon quantum absorption, and the reverse transition was observed upon quantum emission.
