Hierarchical Dual-Mode Efficient Tunable Afterglow via J-Aggregates in Single-Phosphor-Doped Polymer.

Angewandte Chemie
The development of polymer-based persistent luminescence materials with color-tunable organic afterglow and multiple responses is highly desirable for the applications in anti-counterfeiting, flexible displays and data-storage.

Direct in Situ Fabrication of Multicolor Afterglow Carbon Dot Patterns with Transparent and Traceless Features via Laser Direct Writing.

Nano letters (Print)
Multicolor afterglow patterns with transparent and traceless features are important for the exploration of new functionalities and applications. Herein, we report a direct in situ patterning technique for fabricating afterglow carbon dots (CDs) based on ...

Afterglows

2002
Abstract By 1993 most astronomers were convinced, on the basis of the BATSE data and apparently sound theoretical arguments, that gamma-ray bursts occur at cosmological distances, and that they involve relativistic expansion with Lorentz factors of one hundred or more.

Full-Color Dynamic Afterglow in Carbon Dot-Based Materials Regulated by Dual-Phosphorescence Resonance Energy Transfer.

Small
Developing afterglow materials with wide-range and time-dependent colors is highly desirable but challenging. Herein, by calcinating the mixture of Rhodamine B and NH4Al(OH)2CO3, carbon dots (CDs) are generated and in situ embedded in the porous Al2O3 ...

A short duration afterglow of nitrogen; survey of afterglows

Planetary and Space Science, 1959
Abstract When an electron beam of more than 10·5 eV energy traverses low pressure nitrogen the beam is surrounded by a diffuse glow emitting the first positive bands ( 1 ). This light is interpreted as an afterglow. It is attributed to metastable molecules, a 1 Π , which diffuse out of the space occupied by the beam, are thrown by collisions with ...
