Fabrication of quantum dots (qds) with emission covering a wide spectral region has been persistently intriguing because of their potentials in a range of practical applications such as biological labeling and imaging, solar cells, light emitting diodes, and next generation displays. in this work, we report the synthesis of cdznse–cdzns core–shell alloy qds through a cu catalyzed solid. Figure 6. photograph image (top) and pl spectra (bottom) of the cdse cds core shell qds and cdznse cdzns core shell alloy − − − − qds showing the full coverage of the visible spectral range from 470 to 650 nm. during the cooling process after the reaction.85 therefore, overall, cu ions act as catalysts in this alloying process.

Graphical abstract. in order to reduce the emission linewidth of quantum dots (qds), we inhibited the emission of the light hole (lh) state by controlling core–shell strain and then reduced the exciton phonon coupling (epc) by alloying cations. our asymmetrically strained qd ensemble exhibits highly bright emissions with ultra narrow.
