Fig. 8From: Fabrication of a light-emitting device based on the CdS/ZnS spherical quantum dots(a) Absorbance, (b) PL spectra and (c) CIE coordinates of QDs (W = 6). The white light emission is obtained from the mixture of blue and green/orange emission originated from core CdS and the inner shell ZnS, respectively. The excitation wavelength is 휆 = 400푛푚. The CIE coordinates of this white light emission is (0.33, 0.34)Back to article page
