Polar solvent-free room temperature synthesis of CsPbX₃ (X = Br, Cl) perovskite nanocubes

Abstract

Conventionally, the colloidal lead halide perovskite nanocubes have been synthesized by the hot-injection or ligand-assisted reprecipitation (LARP) methods. We herein demonstrate a polar solvent-free room temperature method for the synthesis...

Molecular insights into the growth and time evolution of surface states of CsPbBr3 nanoparticles synthesized using a scalable room temperature approach

“…trioctylphosphine oxide -TOPO -and tetraoctylammonium bromide -TOAB -) [17][18][19][20][21] and ligands. 22 First 17,18 TOAB was used as the solvation and stabilizing agents, then the addition of less sterically hindered alkylammonium bromide was reported 19 to improve the NP stability. More recently, Brown et al 21 employed phosphorous based solvation agents and ligands to afford size control and high emission properties.…”

All-inorganic lead halide perovskites for photocatalysis: a review

“…Guvenc et al produced CsPbX 3 (X = Br, Cl, I) by LARP; the PLQY of synthesized CsPbBr 3 was 85%. 125 By altering the experimental conditions, the LARP method can be used to manufacture all-inorganic lead halide perovskite with various morphologies. Deng et al formed all-inorganic CsPbX 3 perovskite in a variety of shapes, including 0D spherical quantum dots, 1D nanorods, and 2D nanoplates 126 ( Fig.…”
