The photoluminescence of these nanocrystals is attributed to emission from surface defect states. The decay of the excited state in the nanosecond region, which can be analysed as a triple exponential, depends strongly on the emission wavelength selected, but only weakly on the excitation wavelength.||Type of material:||Journal Article||Publisher:||RSC Publishing||Copyright (published version):||2010, Royal Society of Chemistry||Keywords:||Spectroscopy;Chiral;CdSe;Quantum dots||DOI:||10.1039/C0JM01185A||Language:||en||Status of Item:||Not peer reviewed|
