Temperature sensing based on the up-conversion emission of Tm3+ in a single KLuF4 microcrystal
TL;DR: In this paper, the up-conversion (UC) emission intensity of a single KLuF 4 :24%Yb 3+ /0.5%Tm 3+ particle with an average particle size of 5μm has been studied in detail.
Journal ArticleDOI
Optical thermometry based on up-conversion emission behavior of Ba 2 LaF 7 nano-crystals embedded in glass matrix
TL;DR: In this article, Ba2LaF7:Yb3+, Er3+ nano-crystals embedded in a transparent aluminium silicate glass matrix was successfully fabricated by a traditional high temperature melt-quenching technique and the subsequently heat treatment process.
Journal ArticleDOI
Optical temperature sensing properties of KLu2F7: Yb3+/Er3+/Nd3+ nanoparticles under NIR excitation
TL;DR: Yb3+/Er3++/Nd3+ tri-doped KLu2F7 nanoparticles were fabricated via a typical co-precipitation method, and their phase structure, up-conversion (UC) emission and temperature sensing properties were investigated in this paper.
Journal ArticleDOI

TL;DR: The results indicate that the surface states of these UC nanoparticles can be feasibly improved via the post-chemical annealing process without encouraging agglomeration, which further optimizes their UC properties for practical applications.
Journal ArticleDOI
Energy transfer between Ce3+ and Sm3+ in Zn2GeO4 phosphor with the native defects for light-emitting diodes
TL;DR: In this paper, a series of Ce3+, Sm3+-doped Zn2GeO4 phosphors are prepared by the solid-state reaction, and a blue photoluminescence (PL) is observed as the recombination of the electrons trapped on VO• and Zni• with holes trapped on VGe and VZn′.
