Crystallization Behaviors of PbSe Quantum Dots in Silicate Glasses
De-Wei Ma,Cheng Cheng +1 more
TL;DR: In this paper, the authors studied the crystallization behaviors of PbSe quantum dots (QDs) in silicate host glasses, and the results showed that the selected glass compositions have an intermediate fragility and accordingly an intermediate glass transition temperature range among a wide variety of inorganic glass systems together with a good GFA/glass stability.

Effect of topological structure on photoluminescence of PbSe quantum dot-doped borosilicate glasses
TL;DR: In this article, a broad near infrared (NIR) photoluminescence (PL) emission (1070-1330 nm) with large fullwidth-at-half-maximum (FWHM) values (189-266 nm) and notable Stokes shift (100-210 nm) was observed, which depended on the B2O3 concentration.

Influence of Intermediate ZnO on the Crystallization of PbSe Quantum Dots in Silicate Glasses
TL;DR: In this article, the color changes of annealed and as-prepared glasses containing PbSe quantum dots have been investigated using the Gibbs-Helmho1tz equation, and it was shown that the host glass with an introduction of 9.4 wt.% ZnO possesses a maximum degree of crystallization and the best optical properties among all samples.
