Abstract

Doping low-valence ions in core–shell NC is applied to improve negative thermal quenching effect. With the increase in temperature from 293 to 413 K, the UC emission intensity of 20Yb/2Er : NaGdF4 (12 nm) increases by 2.2 times, whereas that of NaGdF₄@20Ca/20Yb/2Er: NaGdF₄ (11 nm) increases by 10.9 times.
