The precursor powder and luminescent ceramics YAG:Ce based on it were obtained by reverse chemical deposition. The influence of sintering additives (CaO, MgO and TEOS), the concentration of the activator Ce3+, the temperature of vacuum sintering, as well as the temperature of air annealing on the luminescent properties of YAG:Ce ceramics has been studied. The following parameters have been identified as optimal parameters for the manufacture of YAG:Ce ceramics in terms of luminescence efficiency. The concentration of the sintering additive is 0.01 f.u., the type of sintering additive is TEOS, the vacuum sintering temperature is 1800 ?C, the air annealing temperature is 600 ?C for samples with TEOS. A sample with a luminescence efficiency of 319 Lm/W was obtained when exposed to 190 mW laser radiation with a spot diameter of ~5 mm.
