Rapid Preparation and Luminescence Properties of YbAG:Tm3+ Nanoparticles

摘要

(TmxYb1 -x)(3)Al5O12 (YbAG:Tm3+) nanoparticles (NPs) with mean diameter of 56 nm were prepared by a rapid carbonate coprecipitation method with a short calcination time of only 1 min. Our results confirmed the structure and purity of the prepared material and proved that Tm3+ was successfully incorporated into YbAG. The results on the upconversion luminescence show that the emission peaks were located at 486 and 684 nm, corresponding to the (1)G(4) H-3(6) and F-3(2) H-3(6) transitions of Tm3+. The transition mechanism of the blue and red emission was discussed.This rapid method could improve the production efficiency of YbAG:Tm3+ nanoparticles, and may have certain implications for the preparation of other upconversion nanomaterials.
