Blue Electrogenerated Chemiluminescence from Halide Perovskite Nanocrystals

Electrogenerated Chemiluminescence and Spectroelectrochemistry Characteristics of Blue Photoluminescence Perovskite Quantum Dots

“…MABr (methylammonium) and the QDs were synthesized according to previously reported literature using ligand-assisted reprecipitation method (LARP). , In a typical synthesis of QDs, 32 mM MABr, 19.9 mM PbCl 2 , and 20 mM PbBr 2 were dissolved in 5 mL of DMF with 20 μL of n-octyl amine and 500 μL of oleic acid. Two milliliters of this precursor solution was then added dropwise to 10 mL of toluene with vigorous stirring for 30 min.…”

“…Halide ion migration, defects, and structure decomposition when exposed to air, heat, moisture, and UV irradiation are among the causes of the stability issues of organometallic halide perovskites. New synthesis methodology and structural engineering techniques are needed to obtain stable perovskite crystal structure for optimal light absorption and carrier transport and stability. − Our team recently demonstrated blue ECL and single QD PL imaging of mixed halide perovskite QDs of CH 3 NH 3 PbCl 1.08 Br 1.92 on glassy carbon electrode . Two distinct ECL peaks at 473 and 745 nm were obtained when ECL was produced with coreactant of tripropyl amine (TPrA).…”

Recent Progress in Electrochemiluminescence of Halide Perovskites

“…Halogen anion adjustable is one of the outstanding characters of PeNCs, which can lead to bright PL emission over the entire visible spectral region. Wusimanjiang et al (2019) synthesized mixed-halogen perovskite of MAPbCl 1.08 Br 1.92 QDs (3.5 nm). Rare sky-blue ECL emission centered at 473 nm was first achieved, demonstrating the feasibility of halogen anion-tunable ECL spectra.…”

Determination of organophosphate flame retardant tris(2‐chloroethyl)phosphine based on the luminol–H2O2 chemiluminescence system

“…[22] CL detection methods are some of the most sensitive and selective detection techniques in analytical chemistry. [23][24][25][26][27] CL has the following advantages. First, compared with other optical reactions, there is no need to excite a light source, which gives rise to a lower background signal, an extremely low detection limit, and a broad dynamic range.…”
