Preparation method of photoluminescent powder, ceramic ink and invisible anti-counterfeiting ceramic

The invention discloses a preparation method of photoluminescent powder, ceramic ink and invisible anti-counterfeiting ceramic, and relates to the technical field of ceramic tile anti-counterfeiting, the preparation method comprises the following steps: step S01, dissolving an oxide A in an acid solution to obtain a solution B; s02, an oxide C is dissolved in an acid solution to obtain a solution D, and the oxide C is a lanthanide metal oxide; step S03, dropwise adding the solution B into the solution D, uniformly mixing, adding an alkaline precipitator, and heating in a water bath until the precipitate is completely separated out; and carrying out centrifugal separation, and washing, drying and high-temperature calcination on the precipitate to obtain the photoluminescent powder. The photoluminescence powder is synthesized through a wet method, the photoluminescence powder can have the good high-temperature-resistant characteristic without being coated, the sintering temperature of 1350 DEG C can be resisted
