摘要:
Luminescent (trimethylbromomethyl) ammonium lead tribromide ((TMBM)PbBr3) nanocrystals are synthesized by a green single-step mechano-grinding method in large scale. The photoluminescence quantum yield (PL QY) of the obtained (TMBM)PbBr3 nanocrystals is 2.61 %. The luminescence of the nanocrystals can be significantly enhanced by introducing water or methanol during the grinding process. The maximum PL QYs of 7.65 % and 4.69 % are obtained for the nanocrystals prepared by the addition of water and methanol, respectively. The emission light of (TMBM)PbBr3 nanocry...
