Fig. 3From: Passivation and Interlayer Effect of Zr(i-PrO)4 on Green CuGaS2/ZnS/Zr(i-PrO)4@Al2O3 and Red CuInS2/ZnS/Zr(i-PrO)4@Al2O3 QD Hybrid PowdersPartial XPS survey results of O component peaks of green a CGS/ZnS and b CGS/ZnS/Zr(i-PrO)4 QDs; and red c CIS/ZnS and d CIS/ZnS/Zr(i-PrO)4 QDs. In the XPS spectra, ZrO2 (red line) peak is deconvoluted from the original O spectra (black line)Back to article page
