<p>We report, for the first time, new insights into the nature of the band gap of <a>CuGeO<sub>3</sub> </a>(CGO) nanocrystals synthesized from a microwave-assisted hydrothermal method in the presence of citrate. To the best of our knowledge, this synthetic approach has the shortest reaction time and it works at the lowest temperatures reported in the literature for the preparation of these materials. The influence of the surfactant on the structural, electronic, optical, and photocatalytic properties of CGO nanocrystals is discussed by a combination of experimental and theoretical approaches, and that results elucidates the nature of the band gap of synthetized CGO nanocrystals. We believe that this particular strategy is one of the most critical parameters for the development of innovative applications and that result could shed some light on the emerging material design with entirely new properties.</p> <p><b> </b></p>

This paper deals with the effect of yttrium doping on the structural and optical properties of zinc sulphide (ZnS) nanoparticles with nanoparticulated mesoporous. The morphology of the nanoparticles is determined by FESEM and it shows that the particles are spherical shape. HRSEM images show that particle size and agglomerated nature of the samples are augmented when doping concentration increases. Transmission electron microscope images probe the spherical shape of the nanoparticles as well as small number of inter particle mesoporous with intra-particles. The selected area electron diffraction images validate the crystalline and cubic nature of the synthesized samples. The presence of intra-particles is corroborated by XRD and FTIR spectra. X-ray diffraction’s results also confirm that the synthesized nanoparticles are crystallized in zinc blende structure. The diffuse reflectance spectra indicate that 5[Formula: see text]wt.% of yttrium-doped zinc sulphide shows higher reflectance than the undoped ZnS. Thus photoluminescence studies suggest that 5[Formula: see text]wt.% of yttrium-doped ZnS sample may be used for the development of supersensitive ultraviolet detector.

We demonstrated phase control, mediated by the presence of tetrabutylammonium hydroxide, in the growth of ZnS crystals by using a cost effective MAS method; a very moderate temperature (140 °C) and a very fast reaction time are sufficient to produce nanostructures with a good degree of crystallinity.
