Journal ArticleDOI
A photocatalytic approach for the reductive decolorization of textile azo dyes in colloidal semiconductor suspensions
TL;DR: In this article, two representative commercially used textile azo dyes, Acid Orange 7 and Direct Blue 1, have been decolorized using colloidal TiO and WO[sub 3] photocatalytic systems.
Journal ArticleDOI
Exciton recombination dynamics in CdSe nanowires: bimolecular to three-carrier Auger kinetics.
TL;DR: Ultrafast relaxation dynamics of charge carriers in CdSe quantum wires with diameters between 6 and 8 nm are studied as a function of carrier density to define an optimal intensity for achieving optical gain in solution-grown nanowires given the different carrier-density-dependent scaling of relaxation rates.
Journal ArticleDOI
Squaraine Rotaxane as a Reversible Optical Chloride Sensor
Jeremiah J. Gassensmith,Sarah Matthys,Jung-Jae Lee,Aleksandra Wojcik,Aleksandra Wojcik,Prashant V. Kamat,Bradley D. Smith +6 more
TL;DR: Association of Cl(-) to immobilized rotaxane induces macrocycle translocation and exposure of the electrophilic C(4)O(2) core of the squaraine station, which is in turn attacked by the ambient moisture to produce a bleached product.
Journal ArticleDOI
Substrate driven photochemistry of CdSe quantum dot films: charge injection and irreversible transformations on oxide surfaces.
Kevin Tvrdy,Prashant V. Kamat +1 more
TL;DR: Fluorescence decay and transient absorption experiments confirmed that charge injection from excited CdSe into TiO2 occurs with an apparent rate constant of 5.62 x 10(8) s(-1) and is the primary event responsible for photodegradation.
Journal ArticleDOI
Metal–metal and metal–semiconductor composite nanoclusters
TL;DR: In this article, a photoinduced bleaching of surface plasmon band has been monitored using a picosecond laser flash photolysis apparatus, where gold capped TiO2 nanoparticles were found to improve the efficiency of interfacial charge transfer process.
