Closed access Metadata (CSL-JSON)
DOI 10.1021/acs.inorgchem.2c00596
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

NaSrR(BO 3 ) 2 (R = Ho–Lu, Y, Sc) compounds were obtained for the first time. Their structures exhibit disordered positions of Sr 2+ and Na + atoms while RO 6 polyhedra are connected through the BO 3 groups. Large distances between R atoms and high transparency in the range of 250–900 nm make them promising for phosphor applications. A pathway to obtain single crystals was shown by growing NaSrY(BO 3 ) 2 and NaSrYb(BO 3 ) 2 by the top seeded solution growth method with Na 2 O-B 2 O 3 -NaF flux.
