Recent Advances in Room Temperature Phosphorescence Materials

Dear Colleagues,

Room-temperature phosphorescence and related materials have attracted tremendous attention recently due to their spectacular photophysical properties and versatile applications in many fields. In particular, the exploration of purely organic room-temperature phosphorescent (RTP) materials is currently the focus of research in organic electronics with broad application areas spanning from information anticounterfeiting, and sensors to afterglow displays and bio-/X-ray imaging. The impressive charm of RTP materials relies on the fact that the significant breakthrough of the modulation of triplet state natures for on-demand achieving outstanding properties and functionalities through easy chemical modification with endless possibilities, revolutionizing the immanent understandings of the excited state characters originated from either organic or organic–inorganic hybrid materials. Even more impressively, the organic afterglow with persistent RTP shows ultralong-lived and persistent luminescence that can last for over 1 s under ambient conditions, demonstrating fundamental advances in performance promotion and application revolution of organic optoelectronic materials.

This Special Issue will compile recent developments in the field of high-performance RTP materials. The articles presented in this Special Issue will cover various topics, ranging from the luminescent mechanisms of RTP and afterglow, the design and characterization of RTP materials, to advanced optoelectronic applications in the fields of information encryptions, displays, programmable label and X-ray imaging, etc.
