Observation of electron–phonon coupling and linear dichroism in PL spectra of ultra-small CsPbBr3 nanoparticle solution

Observation of electron–phonon coupling and linear dichroism in PL spectra of ultra-small CsPbBr3 nanoparticle solution

Blue-emission (∼480 ​nm) CsPbBr3 nanoparticles with ultra-small size (∼2.1 ​nm) are synthesized using the liquid nitrogen freezing with the ligand of dodecylbenzene sulfonic acid (DBSA). Asymmetric narrow emissions at the low energy side, with the full width at half-maximum of ∼20 ​nm, are observed...
