A universal supramolecular assembly strategy for achieving efficient tunable white emission and anti-counterfeiting in antimony doped tin(iv)-based vacancy-ordered double perovskites

Three compounds with high PLQY, (AC) 2 SnCl 6 :Sb 3+ (A = K, Rb, and Cs), were developed using a supramolecular assembly strategy. The samples doped with Sb 3+ were used to achieve tunable WLEDs, anti-counterfeiting, and information encryption.
