Synthesis method of ultraviolet-excited multicolor emission fluorescent powder

The invention provides a synthesis method of ultraviolet-excited multicolor emission fluorescent powder, which comprises the following steps: weighing corresponding oxides, carbonates and phosphates,mixing the weighed substances, uniformly grinding the mixture in an agate mortar, putting the agate mortar into a corundum crucible, putting the corundum crucible into an oven, presintering the mixture at 200 DEG C for 2 hours under the air condition, cooling the mixture to room temperature, taking out and grinding the mixture, putting the mixture into the corundum crucible, and then roasting for7-10 hours at the temperature of 800-1000 DEG C in the atmosphere of activated carbon and carbon monoxide, naturally cooling the mixture to room temperature, and taking out and uniformly grinding themixture to obtain a white powder. The multi-color emission fluorescent powder prepared by the method overcomes the defects of poor color rendering property and narrow excitation wavelength of the traditional fluorescent powder,
