FIG. 1.

(Color online) Three-dimensional AFM image of CdSe QDs deposited on ZnCdMgSe barrier . Inset shows a histogram of the QD height.

FIG. 2.

(Color online) PL spectra of five samples grown with different CdSe deposition times. The PL peak emission and for each sample is indicated in parenthesis.

FIG. 3.

(a) Variation of the PL emission energy and (b) of FWHM with for several samples grown on different days. The different symbols indicate the different days the samples were grown.

Image of FIG. 4.
FIG. 4.

PL spectrum of an R-G-B MQD sample with white emitted light color at . PL peak emissions with their corresponding assignments are indicated in the figure (red QD layer , green QD layer , blue QD layer ). ZnCdMgSe barrier peak can be noticed in the figure at .

Image of FIG. 5.
FIG. 5.

(Color online) White light emitted for the R-G-B MQD structure represented in Fig. 4. The sample was mounted on the cold finger of a Janis cryostat, which can be clearly distinguished in the figure.
