Anomalous spectral characteristics of ultrathin sub-nm colloidal CdSe nanoplatelets

Conference name: CLEO: Science and Innovations 2017 Date of Conference: 14–19 May 2017 We demonstrate high quantum yield broad photoluminescence emission of ultrathin sub-nanometer CdSe nanoplatelets (two-monolayer). They also exhibit polarization-characterized lateral size dependent anomalous heavy hole and light/split-off hole absorption intensities. © 2017 IEEE.
