The development of a reversible chemical sensor based on a CdSe/ZnS nanocrystal (NC) is
described. Signal transduction is accomplished by fluorescence resonance energy transfer (…

Semiconductor nanocrystals (NCs) are attractive as lasing media given their photostability,
spectrally narrow gain profile, wide color tunability, and ease of chemical processing.[1±3] …

We demonstrate tunable room-temperature amplified spontaneous emission and lasing
from blue-emitting core-shell Cd S∕ Zn S nanocrystals (NCs) stabilized in a sol-gel derived …

We have studied manganese doping of zinc selenide core/zinc sulfide shell nanocrystals (NCs)
where the impurity phosphor resides primarily in the shell. We have found that a simple …

This communication describes a long (1 cm), laser-pumped, liquid core−liquid cladding (L 2
) waveguide laser. This device provides a simple, high intensity, tunable light source for …

Semiconductor nanocrystals, or quantum dots (QDs), are candidates for biological sensing,
photovoltaics, and catalysis due to their unique photophysical properties. The most studied …

Many types of metal and semiconductor nanoparticles (NPs) are created via colloidal
synthetic methods, which renders the materials hydrophobic. Such NPs are dispersed in water …

We report here a method for synthesizing CdSe quantum dots (QDs) containing copper
such that each QD is doped with four copper ions. The synthesis is a derivative of the cluster-…

We have created a platform for the ratiometric fluorescent sensing of targeted proteins by
conjugating conjoined protein binding agent/organic dye ligands to water-soluble, emissive …

The reactivity of triplet 16-electron organometallic species has been studied in room-temperature
solution using femtosecond UV pump IR probe spectroscopy. Specifically, the Si−H …
