Zusammenfassung: | The invention discloses a preparation method of an anti-counterfeiting material based on a multi-response platinum lighting-emitting and color-changing complex and application of the anti-counterfeiting material and belongs to the field of application of visible light lighting-emitting and color-changing materials. After the anti-counterfeiting material is treated with 1,2-dichloroethane and chloroform steam, the colors of two samples are yellow incapable of being distinguished with naked eyes, under irradiation of an ultraviolet lamp, the two samples give out yellow light, and the positions of emission peaks are the positions of 536 nm. When the two samples are heated at the temperature of 50 DEG C, the color of the sample treated with 1,2-dichloroethane is changed into orange red, the color of the emitted light is changed into bright red, and the position of the emission peak is the position of 693 nm. The color and emitted light of the sample treated with chloroform are not affected by heating. The anti-co |
