Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The work presents results of a study of the pulsed cathodoluminescence uranium doped LiF crystals. Introduction of the activator (U) and the co-activator (OH) shown in occurrence of additional absorption in the range 260-320 nm. The activated crystals luminescence observed in the field of 400-530 nm when excited by pulsed electron beam with energy 250 keV. In all crystals, the main attenuation component has a value in the range of 40-70 μs. Crystals of lithium fluoride, activated by uranium, with injected coactivators can have highly efficient conversion of radiation energy into light in the visible range of the spectrum.
