This invention relates to the field of
encryption and anti-counterfeiting technology, specifically to a method for preparing and using an organic Sn(IV)-based
metal halide reversible light-emitting conversion triple anti-counterfeiting material, comprising introducing organic ligands into a Sn(IV)X4 lattice and
doping with ns 2 This invention uses Sn(IV) with a high
oxidation state to replace Pb(II) in order to obtain anti-counterfeiting materials. 4+ The outer
electron configuration is 4d 10 5s 0 The absence of unstable 5s orbitals gives Sn(IV)-based
metal halides their typically excellent environmental and
thermal stability, providing the compounds with a rigid
crystal structure and stereochemical inertness. Furthermore, through ns... 2 Type Sb
