Triple-mode tunable long-persistent luminescence in a 3D zinc-organic hybrid

Abstract

A 3D zinc-organic hybrid [Zn₃(D-Cam)₃(tib)₂]·2H₂O (1) exhibits triple-mode dependent (including excitation wavelength, time and temperature) long-persistent luminescence. Experimental and theoretical calculations support that the long lifetime and color-tunable afterglow may be due to the dispersive electronic state distribution. Furthermore, the hybrid is also used for optical anti-counterfeiting and information encryption applications.
