Figure 2From: An effective oxidation approach for luminescence enhancement in CdS quantum dots by H2O2XPS spectra. The spectra correspond to (a) Cd 3d, (b) O 1 s, and (c) S 2p for the CdS nanocrystals with various amounts of injected H2O2 solution. The dashed lines on each spectrum are from [26] and [27].Back to article page
