Reversible thermochromism of CsPbBr3-doped tellurite glass

Abstract

Perovskite quantum dots (PQDs) have emerged as a promising research field and dynamic modulation of PQDs could induce reversible color alterations of PQD-doped glass. In this study, the incorporation of PQDs imparts reversible thermochromic properties to traditional tellurite glass, manifesting a reversible transition from a vibrant yellow hue to a pristine colorless state at a temperature lower than that previously documented for PQD-infused silicate glass. Detailed analyses encompassing variations in transmittance, absorption edge, optical bandgap, and Urbach energy between precursor glass (PG) and PQD composite glass (GC) elucidate the pivotal role of PQDs in this transformation. These findings underscore the rich physicochemical properties and potential applications of PQD-doped glass, highlighting their significance in materials science.
