Preparation method and application of AgCl glass powder with photochromic effect

The invention discloses a preparation method and application of AgCl glass powder with a photochromic effect. The invention designs a preparation method and application of glass powder with a photochromic effect, which belong to the technical field of anti-counterfeiting application. The preparation method comprises the following steps of weighing 15% by mole of SiO2, 5% by mole of Al2O3, 33.9% by mole of B2O3, 4% by mole of ZnO, 10% by mole of SrCO3, 30% by mole of GeO2, 2% by mole of AgCl and 0.1% by mole of Cu2O into an agate mortar, grinding and uniformly mixing, heating to 1300 DEG C in an air atmosphere, sintering for 25 minutes to obtain glass without a color change effect, annealing the glass at 600 DEG C for 1-2 hours, cooling to room temperature along with a furnace, grinding into powder, and acquiring the glass powder with the photochromic effect. The glass powder with the photochromic effect is prepared, the glass powder is changed from white to black under 365nm ultraviolet irradiation, so that t
