“…The spectrum shown in Fig. 3 was recorded in two segments and joined together, which is revealed by a discontinuity at 615 nm.All these centers were known to occur in LiF [1][2][3][4][5][6][7][8][9]. The material exhibited bright orange emission on exposure to Ar ion or a dye laser even at room temperature.…”

“…Conventional spectroscopy of this material was done extensively [1][2][3][4][5][6]. The nature of the induced centers depends on the type of radiation and dosage used as well as on the temperature of the material during exposure [7][8][9]. Most of the centers are unstable at room temperature except for the F 2 center.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
