Grinding Ammonium Method

Mar 01, 2021 Luminescent (trimethylbromomethyl) ammonium lead tribromide ((TMBM)PbBr 3) nanocrystals are synthesized by a green single-step mechano-grinding method in large scale.The photoluminescence quantum yield (PL QY) of the obtained (TMBM)PbBr 3 nanocrystals is 2.61 %. The luminescence of the nanocrystals can be significantly enhanced by introducing water or methanol during the grinding
