About this Research Topic
Room-temperature phosphorescence (RTP) from metal-free materials has become a feature that has defined a completely new and broad research direction. Observed as a persistent luminescence, RTP can be utilized in a variety of imaging fields as it offers high-resolution and brightly-emitting information from the specimen, that is independent from the autofluorescence in the time domain and further spectrally distinct, given the dual-color emission of fluorescence and RTP. These are luminescent properties that fluorescent materials and phosphorescent heavy metal-complexes do not possess. State-of-the-art security applications, sensor systems and bioimaging methods using these features have been demonstrated. Recent emergence of a variety of materials showing metal-free RTP inspires us to consider new strategies of more efficient metal-free RTP and diverse applications using their unique characteristics.
This Research topic will focus on the metal-free RTP materials design, characterization and physicochemical studies. We welcome articles focused on the design of chromophores and their crystalline structures. Equally, we encourage contributions that focus on deepening the understanding of RTP and the various related structure-property relations. Ideas of innovative applications using the novel materials and their integration in other technologies are also welcome.
The goal of this collection is to provide a central venue for researchers with interest in metal-free RTP phenomena to inspire diverse discussions in this new and rapidly growing community uniting various research backgrounds and development directions.
We welcome Original Research, Review, Mini Review and Perspective articles on themes including, but not limited to:
• design, development and characterization of high-efficiency afterglow RTP compounds, with a special emphasis on red and near-infrared emitters
• studies on the mechanisms towards control and/or enhancement of RTP and/or persistent emission;
• novel experimental and/or theoretical procedures to further analyze RTP and/or persistent emission;
• innovative applications of novel RTP and/or persistent emitting materials in time-scale imaging (lifetime imaging) including dynamic and/or photo-induced RTP
Unique and state-of-the-art demonstrations of application-scenarios leading to an expansion of the use of metal-free RTP and/or persistent emitting materials would be most welcome.
