Data confidence 70 medium

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 research and development of new VUV scintillators includes also LuLiF4 single crystals doped by${\hbox{Nd}}^{3+}$. Due to their lower light yield, the${\hbox{Gd}}^{3+}$codoping is studied as a tool to improve an energy transfer from the host to${\hbox{Nd}}^{3+}$emission centers and increase the light yield consequently. Emission spectra and decays with respect to the different concentration of Gd and Nd ions are studied and discussed as well.
