“…As an example, semiconductor nanocrystals (quantum dots) are used in medical applications as fluorescent tags [1,2] LEDs [3,4] or tunable lasers [5,6] in optical applications, or for energy conversion in photovoltaic cells [7,8], or metal nanoparticles in catalytic applications [9]. Accompanied with the extensive attention in these fields, the optical behaviors of quantum dots nanomaterials with polymers have intrigued considerable research interest [10,11].…”

Thin UV-blocking films of poly(methyl methacrylate) and CdSe quantum dots (QDs) (CdSe@PMMA) are built up by CdSe-azo initiator through surface-initiated free-radical polymerization. CdSe@PMMA nanocomposite film possesses excellent transparency and ultraviolet (UV)-shielding properties. The average size of CdSe QDs is found to be less than 5 nm and well dispersed in the PMMA matrices without any significant agglomeration by the transmission electron microscopy (TEM) measurement. At the same time, excellent fluorescence (FL) spectra of the nanocomposite indicate that the luminescent properties of CdSe QDs remain effective after the polymerization. Such the transparent and luminescence CdSe@PMMA nanocomposite film exhibits prominent UV-absorbing capability and the high optical transparency in the visible-wavelength region, thus make it to be a promising material for the large scale fabrication of diverse optical devices.

“…Various methods, such as anodic aluminum oxide (AAO) template-assisted synthesis [8], hydrothermal process [9], solution-liquid-solid (SLS)-assisted growth [10,11], seeded-type growth [12] and single-source molecular precursor route [13,14] have been developed and extensively studied. However, harsh conditions, complicated reagents, usage of sacrificial templates or guiding catalysts are required in these processes, which may complicate the application of the nanostructures.…”

The electrical properties of Cadmium Selenium (CdSe) nanoparticles were measured by using I-V characteristic under illumination of light (AM 1.5, 100mWcm-2) at room temperature. The cadmium chloride (CdCI) as the Cd precursor and selenium (Se) powder as the Se precursor. In this research, the surface profiler was used to know the thickness of CdSe nanoparticles on the glass substrate. The thickness was used to know the energy band gap by using Tauc plot. The optical properties was measured by using Photoluminescence (PL) at room temperature. The energy band gap for 20 min ,30 min ,40 min and 50 min were 4.25 eV, 4.22 eV, 4.09 eV, and 4.21 eV.

Core/multishell CdSe/CdS/CdS/Cd0.75Zn0.25S/Cd0.5Zn0.5S/Cd0.25 Zn0.75S/ZnS/ZnS QDs/PMMA bulk nanocomposites were successfully synthesized. To achieve a homogeneous and stable dispersion in MMA monomers, QDs were first modified with amphiphilic polymer of poly(ethylene glycol)‐oleate (PEG‐oleate). Subsequently, the transparent and homogeneous bulk composites were obtained by photopolymerization. The TEM analysis of ultramicrotome cut of composite demonstrates that QDs are well dispersed in the PMMA matrix. UV–vis transmission spectra show the nanocomposites still maintain high transmittance even with QDs content of up to 6 wt %. The thermogravimetric analysis (TGA) reveals the incorporation of the QDs significantly improves the thermal stability of composites, as evidenced by the retardation of a degradation initiation by 60°C. Photoluminescence spectra suggest that the nanocomposites exhibit bright fluorescence under UV excitation. X‐ray excited luminescence spectra show they have response to X‐ray. All of the experimental results indicate the great promising applications of core/multishell QDs/PMMA nanocomposites in optical communication devices and radiation detectors. © 2013 Wiley Periodicals, Inc.
