“…Since Bhargava et.al reported the novel properties in nanosized ZnS doped with Mn +2 ions [9], many studies have been published on Ti, V, Cr, Mn, Fe, Co, Ni, Cu and rare earth metal ions activated II-VI, III-V and I-III-VI nanometer scale semiconductor materials [10,17]. Commonly used techniques for the synthesis of II-VI semiconductor Q-dots includes solid-state reaction, sol-gel, microwave electromagnetic radiation, hydrothermal [18][19][20][21]. During the wet chemical synthesis of nanoparticles, organic stabilizers are usually used to prevent them from aggregating by capping their surfaces.…”

The room-temperature photoluminescence of Cd 1−x M x S (M=Ni, Fe) nanoparticles were investigated. Compared with the photoluminescence of CdS which peaks at 475 nm, the photoemission of CdS:Fe nanoparticles was peaking at 537 nm because of Fe acting as luminescent centers. On the other hand, the green emission (503 nm) of CdS:Ni attributed to the 1 T 2g (D)→ 3 A 2g (F) raditive transition. With the increase of the Ni +2 concentration, photoluminescence intensity is increased while by Fe replacement with Cd ions, PL intensity is decreased. Relative to bulk crystals, due to the quantum confinement effect the band gap of CdS clusters is significantly blue-shifted with decreasing cluster size. CdS nanoclusters present a mixed hexagonal/cubic structure and with increasing doping concentration the peaks position of doped CdS shifts to higher angle.

“…nanoparticles exhibit wider energy gap and quantum size confinement. Recently, ZnS nanoparticles have been synthesized by various methods, including solid-state reaction, sol-gel process and hydrothermal method, but some of them require longer processing time or higher temperature [7][8][9].…”

“…They presented experimental evidence that the intercalated PEO had a planar zigzag structure similar to its conformation in a complex with HgCl 2 . The intercalation of oligomeric ethylene oxide esters into CdS, CdSe, and ZnS follows a direct template mechanism, in contrast to what occurs in the case of Ag 2 S, CuS, and PbS under identical conditions[150]. From aqueous solutions of PEI and MoS 2 , MoSe 2 , TiS 2 , or MPS 3 (M = Mn, Cd), Sun et al…”

This review focuses on organic-inorganic hybrid nanocomposites, a research area that has made rapid progress in recent years. Inorganic components (hosts) include both natural materials (clays, silicates, smectites, layered phosphates, and others) and compounds prepared by different synthetic techniques. Into their interlayer spaces, various organic guests-solvents, monomers, and polymers-can be intercalated. Among the hybrid nanocomposites analyzed in detail are those based on polyconjugated electrically conducting polymers, such as poly(aniline) and poly(pyrrole), and various mineral matrices. Particular attention is paid to polymermetal chalcogenide nanocomposites and their applications as semiconducting materials. One of the most common and practically important intracrystalline processes in the fabrication of hybrid nanocomposites is the incorporation of monomer molecules into pores of the host, followed by controlled internal transformations into polymer, oligomer, or hybrid-sandwich products (in situ postintercalative transformations). This approach is often called "ship-in-the-bottle" polymerization. Another widely used approach is the incorporation of macromolecules into layered host lattices from solutions or melts. This process offers the possibility of producing graphite intercalation compounds and inorganic-organic multilayer composites, including self-assembled nanocomposites in the form of ( P / M ) n multilayers, where M and P are oppositely charged inorganic and polymer nanolayers.
