2D/3D Heterojunction perovskite light-emitting diodes with tunable ultrapure blue emissions

Multiple-cation wide-bandgap perovskite solar cells grown using cesium formate as the Cs precursor with high efficiency under sunlight and indoor illumination

“…The fast component can be attributed to charge carrier trapping at perovskite grain boundaries and the longer time constants ( τ 1 ) mean longer recombination times. 37–39 Hence, longer time constants ( τ 1 ) of the CsFa-perovskite confirm that the probability of carrier trapping and recombination at the perovskite grain boundary is lower within the CsFa-perovskite.…”

Highly Electrochemiluminescent Cs4PbBr6@CsPbBr3 Perovskite Nanoacanthospheres and Their Application for Sensing Bisphenol A

“…Recently emerging perovskite QDs (PQDs), − have become one of the most attractive nanomaterial ECL luminophores since they have high ECL quantum yields and very narrow ECL emission peaks, − and are very easy to prepare . However, as a new type of ECL luminophore, the ECL sensing applications of PQDs still face several challenges.…”

Healthy and stable lighting via single-component white perovskite nanoplates

“…According to the quantum confinement effect, sky-blue CsPbBr 3 nanoplates (NPLs) were employed to avoid deep blue light. 43,44 Then based on a facile post-doping process, CsMn x Pb 1−x Br 3 NPLs emitted healthy white photoluminescence (PL) covering the entire visible spectrum without deep blue light (460-730 nm). On tuning the suitable Mn 2+ doping ratios, white light exhibited a large range of tunable color temperatures from 2000 to 10 000 K. Benefiting from Mn 2+ doping to induce lattice shrinking, CsMn x Pb 1−x Br 3 NPLs exhibited enhanced stability toward long-term storage, UV light, heat, and polar solvents.…”
