Figure 6From: CdTe Quantum Dot/Dye Hybrid System as Photosensitizer for Photodynamic TherapypH dependence of PL intensity for 3.3-nm NC set. The PL intensity of NCs increases at higher pHs due to better chemical stability. In the presence of MB, complete quenching is not observed for higher pHs even for 10 MB:QD molar ratio because the electrostatic interactions between NCs and MB are altered by high ionic strengthBack to article page
