PbS nanocrystals are synthesized using colloidal techniques and have their surfaces
capped with oleic acid. The absorption band edge of the PbS nanocrystals is tuned between …

Inorganic/polymeric composites represent an important and growing class of materials with
promising physical and optical characteristics. Recently new nano composites based on …

Highly luminescent semiconductor quantum dots have been synthesized in porous materials
with ultraviolet and x-ray lithography. For this, the pore-filling solvent of silica hydrogels is …

Light-emitting diodes (LED) are widely employed in display applications and lighting
systems. Further research on LED that incorporates carbon nanostructures and metal …

We demonstrate the effect of surface passivation of cadmium selenide quantum dots (CdSe
QDs)(∼ 5–7 nm) by tri-n-octylphosphene-oxide (TOPO) and oleic acid (OA) on the structural …

The surface modification of lead chalcogenide epitaxial films during plasma treatment
processes is investigated. With AFM and SIMS measurements it was shown that the …

A multi-layered nanocomposite thin film was fabricated to increase the density of PbSe
quantum dots. It consisted of low-loss polymer layers and multi-stacked PbSe quantum dot …

The presented investigations aim to pinpoint the crossover of lead sulfide (PbS) quantum
dots (QDs) with a shrinking diameter to a molecular state. We have measured the …

CuS hollow nanospheres have been successfully synthesized in high yield by reacting
anhydrous cupric sulfate (CuSO 4· 5H 2 O) with thioacetamide (TAA) in ethylene glycol (EG) …

Optical properties of lead chalcogenide quantum dots (QDs) can be controlled by tuning its
bandgaps. We prepared silicate glasses using the melt-quenching method and heat-treated …
