The influence of phthalocyanine aggregation in complexes with CdSe/ZnS quantum dots on the photophysical properties of the complexes
نویسندگان
چکیده
The formation of nonluminescent aggregates of aluminium sulfonated phthalocyanine in complexes with CdSe/ZnS quantum dots causes a decrease of the intracomplex energy transfer efficiency with increasing phthalocyanine concentration. This was confirmed by steady-state absorption and photoluminescent spectroscopy. A corresponding physical model was developed that describes well the experimental data. The results can be used at designing of QD/molecule systems with the desired spatial arrangement for photodynamic therapy.

P-156: A Study about Toxicity of CdSe Quantum Dots on Male Sexual System of Mice and Controlling This Toxicity by ZnS Coverage in Immature Mice
Background: Quantum dots are commonly composed of cadmium contained semiconductors. Cadmium is potentially hazardous but toxicity of such quantum dots is not yet systematically investigated. On the other hand, in vitro studies have shown almost complete control of CdSe induced cytotoxicity by ZnS coverage. Toxicity of CdSe quantum dots and controlling this toxicity by ZnS coverage in immature m...

متن کاملCoupling of CdSe/ZnS quantum dots: among themselves and with matrices
We investigate the photoluminescence (PL) properties of CdSe/ZnS quantum dots (QDs) deposited on Si, fused silica, Au film, and silica nanospheres. The red shifts of the PL peak were observed with increasing density of QDs on various matrices: Si, fused silica, and Au film. This red shift is attributed to coupling between QDs forming bonding and anti-bonding states with PL emerging from the low...
