PL FWHM, peak site, and QYs of CdSe/ZnS NCs for varying shell growth cycles
	Cycles of reaction (times)	Sample	Reactionsatime (min)	FWHM (nm)	Peak site (nm)	QYs (%)
CdSe/ZnS	1	a	50	53.4	551.9	4
	2	b	50	42	563.8	25
	3	c	50	42.4	569.4	36
	4	d	20	42.6	570.4	29
		e	50	43.2	573.4	22

^aAliquots were taken at different times for monitoring the reaction of shelling every cycle. As the number of samples is high, here we have selected the representative ones
