Abstract

Designing high-performance organic scintillators has drawn massive attention for taking advantages of organic frameworks in practical applications. Obtaining large-area scintillating screens efficiently is in high demand for developing organic scintillators. Herein, we developed two pure organic scintillating materials bearing heavy halogen atoms using a simple one-step method. Excitingly, ICzTPN-based scintillating imaging screen has achieved various advantages against the other organic counterparts, i.e., radioluminescence in lower-energy region (reddish-orange color emission, 600 nm), large size (15 cm × 15 cm), high light yield (19094 photons MeV⁻¹), and ultrahigh resolution (28.3 lp/mm). This work offers an efficient design and preparation of pure organic scintillating materials, providing large-area screen with performance ranking at the top level among the reported organic scintillating imaging screens.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
