Homogenous, far-reaching tuning and highly emissive QD–silica core–shell nanocomposite synthesized via a delay photoactive procedure; their applications in two-photon imaging of human mesenchymal stem cells

Ordered dispersion of ZnO quantum dots in SiO2 matrix and its strong emission properties

“…Therefore, ZnO QDsSiO 2 is considered to be challenging systems for the quantum confinement of semiconductor nanocrystallites for a better control of shape, size and properties [15]. The preparation of such SiO 2 coated QDs is usually done following two techniques: (1) StÖber method [16][17][18][19][20] and (2) reverse microemulsion method [21][22][23][24][25]. The former consists of two steps: (i) preparation of QDs and (ii) then dispersion of the QDs in the SiO 2 matrix.…”

CdSe/CdS-quantum rods: fluorescent probes for in vivo two-photon laser scanning microscopy

“…Because of their exceptionally high uorescence quantum yields core/ shell structured nanocrystals, especially CdSe/ZnS-and CdSe/ CdS/ZnS-QDs, have been investigated most intensively. It was shown that core/shell-QDs are excellent probes for TPLSM, [7][8][9][10][11][12] a technique that allows for deep tissue imaging with reduced autouorescence background, and intrinsic depth sectioning properties. 13,14 Recently, we developed a method for in vivo spectral imaging of different cell types in the small intestine of mice by TPLSM.…”

Freestanding Ag2S/CuS PVA films with improved dielectric properties for organic electronics

“…Usually, silica‐capped nanoparticles are prepared through Stober method and reverse micoemulsion method which involves multiple complicated steps. The silica‐capped Ag 2 S, CuS, Ag 2 S/CuS alloy, and Ag 2 S/CuS nanocomposite particles were synthesized through a sol–gel process with tetraethyl orthosilicate (TEOS) as precursors in the presence of ethanol .…”
