Luminescent Pb-free perovskites: low-cytotoxicity materials for primary thermal sensing

Abstract

Novel luminescent In-based lead-free double halide perovskites co-doped with Yb3+/Er3+ have been synthesized. Their primary thermometer performance was assessed and their biological application to predict temperature was evaluated.

Unlocking the potential of perovskite-based nanomaterials for revolutionary smartphone-based sensor applications

“…[50][51][52][53] This attribute is critically advantageous for incorporation into smartphone platforms, where inherent optical limitations of the devices can be effectively compensated by the remarkable brightness and tunable emission properties. 54 The high surface-to-volume ratio and rapid electron transfer capabilities inherent to Perovskite-based nanomaterials are fundamental for the efficient transduction of biological interactions into electrical signals. [55][56][57] This characteristic substantially enhances the performance of smartphone-based sensors in providing immediate and accurate biological analysis.…”
