“…The observed d-values and respective prominent peaks correspond to the reflection from the (1 1 1), (2 2 0) and (3 1 1) planes, which coincide well with the JCPDS data [27]. The results of X-ray analysis well agree with earlier reported method [14,[22][23][24][28][29][30][31][32][33][34]. From this it can be concluded that the deposited CdSe films are poly-crystalline in nature with cubic modification.…”

“…CdSe thin films can be deposited by various techniques such as vacuum evaporation [1,5,15], electro-deposition [16,17], spray pyrolysis [18,19], thermal evaporation [20], successive ionic layer adsorption and reaction (SILAR) [21] and chemical bath deposition (CBD) [22][23][24]. Among these methods chemical bath deposition (CBD) has greater advantages than others.…”

CdSe films have been deposited on glass substrates at different substrate temperatures between room temperature and 300 °C. The films exhibited hexagonal structure with preferential orientation in the (002) direction. The crystallinity improved and the grain size increased with temperature. Band gap values are found decreasing from about 1.92 eV to 1.77 eV with increase of the substrate temperature. It is observed that the resistivity decreases continuously with temperature. Laser Raman studies show the presence of 2 LO and 3 LO peaks at 416 cm -1 and 625 cm -1 respectively.

A method that does not employ hot-injection techniques has been developed for the size-tunable synthesis of high-quality CdSe quantum dots (QDs) with zinc blende structure. In this environmentally benign synthetic route, which uses less toxic precursors, solvents, and capping ligands, CdSe QDs that absorb visible light are obtained. The size of the as-prepared CdSe QDs and thus their optical properties can be manipulated by changing the microwave reaction conditions. The QDs were characterized by XRD, TEM, UV/Vis, FTIR, time-resolved fluorescence spectroscopy, and fluorescence spectrophotometry. In this approach, the reaction is conducted in open air and at a much lower temperature than in hot-injection techniques. The use of microwaves in this process allows for a highly reproducible and effective synthesis protocol that is fully adaptable for mass production and can be easily employed to synthesize a variety of semiconductor QDs with the desired properties. Possible applications of the CdSe QDs were assessed by deposition on TiO(2) films.
