Ultrasensitive turn-on luminescence humidity sensor based on a perovskite/zeolite composite

Abstract

Recently, the detection and quantification of humidity has attracted great interest, but for fluorescence sensing of humidity, it is still a challenge to achieve high-performance. Here, we report an ultrasensitive...

Reversible human-temperature-responsive luminescence switching in a Mn(ii)-based metal halide

“…Stimuli-responsive luminescent materials, with a specific response to external stimuli such as light, 1 pressure, 2 solvent molecules, 3 and heat, 4,5 have attracted extensive research interest and have shown wide application potentials in information storage, [6][7][8] chemical sensing, [9][10][11] and anti-counterfeiting. [12][13][14][15] In particular, thermosensitive materials are praised for their simple heating device requirement, highlighting their applications in thermal imaging, and thermometers.…”

Na7[SbW6O24]: a new type of turn-off luminescence humidity sensor based on a lanthanide-free polyoxometalate

“…For each RH range, the sensitivity of detection (S) is defined as S = D% PL loss / D% RH i.e., the slope of the calibration curve. 58 % PL loss evolves in three distinct regimes. It strongly increases in the range of 0-23%, with S = 1.30/% RH.…”

Shape-controlled synthesis of one-dimensional cesium lead halide perovskite nanocrystals: methods and advances

“…68,77,78 The mechanism of this transformation is that Cs 4 PbX 6 NCs in nonpolar solvent lose CsX at a nonpolar solvent/water interface owing to good solubility of CsX in water and thus convert into CsPbX 3 NCs. [79][80][81][82][83][84][85] Employing this principle, CsPbBr 3 NWs or NRs can be produced via direct or indirect transformation from Cs 4 PbX 6 NCs. 36,38,41,49,50 Zhang et al first applied this method and prepared ultrathin CsPbBr 3 NWs with a diameter of 2.5 nm and a length of up to 10 mm.…”
