Report the application of synchronous luminescence spectroscopy to detect luminescence centers in colloidal nanocrystals and the emission peaks at 460 and 515 nm which are attributed to the emission transitions related to sulfur and zinc/cadmium vacancies. The obtained results are useful to clarify the nature of luminescence centers as well as relaxation mechanism in CdxZn1−xS nanocrystals. | Detection of luminescence centers in colloidal nanocrystals by synchronous luminescence spectroscopy
