A metal-free 2D layered organic ammonium halide framework realizing full-color persistent room-temperature phosphorescence

Abstract

Organic-inorganic hybrid metal halides have attracted intensive attention because of their unique electronic structure and solution processability. They have rigid micro/nano structure and heavy atom effect, which has obvious advantages...

A promising 1D Cd-based hybrid perovskite-type for white-light emission with high-color-rendering index

“…57–59 On the other hand, Br − ⋯H + hydrogen interactions can inhibit the molecular vibrational movement which improves the luminescence properties. 60 As shown in the structure description section, the XRD results demonstrate the existence of C–H⋯π and Br⋯π interactions between the different organic molecules (see Fig. S2 and S3†).…”

Regulation strategy of white emission from organic–inorganic hybrid metal halide perovskites

“…In particular, the development of metal-free perovskites with white light emission is also a promising direction. 136…”

“…In particular, the development of metal-free perovskites with white light emission is also a promising direction. 136 (4) In-depth understanding about the photophysical mechanism of white emission. The broad-band white light emission of OIHPs often contains multiple emission centers derived from inorganic or/and organic excitons.…”

Halide-containing organic persistent luminescent materials for environmental sensing applications

“…Similarly, the flexible material design of doping systems makes it easy to realize colourful OPL emission by changing the guest molecules. 95,96 Remarkably, ultralong luminescence with emission lifetimes greater than 1 hour can be achieved in pure organic doping systems. 32,92,97–99…”
