Organic room temperature phosphorescence enhancement by grinding and adding water for humidity detection and anti-counterfeiting printing

Abstract

By virtue of the sensitive water response characteristics of a doped material, anti-counterfeiting printing and humidity detection based on this material have been demonstrated.

Cucurbit[8]uril-based host–guest complexation enhancing afterglow of a naphthalimide derivative for anti-counterfeiting printing

“…Long-lived organic room temperature phosphorescent (RTP) materials with afterglow have great potential applications in optoelectronic devices, 1–3 information security 4–6 and biological imaging, 7–9 due to their unique photophysical properties such as long lifetime, large Stokes shift, and high signal-to-noise ratio. 10 In recent years, significant efforts have been devoted to exploring pure organic RTP materials on account of their affordability, facile structural modification and high biocompatibility.…”
