Arrays of nanorods composed of ZnO nanodots exhibiting enhanced UV emission and stability

“…31 Silicon oxide (SiO 2 ) has been employed as a shield, with the aim of improving the optical properties and stability of ZnO nanomaterials. [32][33][34][35] Previous studies have reported that SiO 2 -coated ZnO NRs display high sensitivity towards detecting ultraviolet (UV) photons 36 and biomolecules, 37 good UV-durable superhydrophobicity, 38 and enhanced UV emission. 39,40 Conversely, heterogeneous ZnO ND/SiO 2 structures reportedly show enhanced visible emission 41 but negative photoconductivity.…”

A sol–gel method for preparing ZnO quantum dots with strong blue emission

“…Lu et al [22] reported the synthesis of ZnO QDs with blue emission by annealing zinc sulfide nanoparticles in air atmosphere at 600 1C. Li et al [23] reported bulk preparation of blue-emitting ZnO-QDs-silica/ epoxy super-nanocomposites by an ultrasonic technique via dispersion of ZnO-QDs/silica nanocomposite particles with a matching refractive index in the transparent epoxy matrix. Chakraborti et al [24] reported the emission spectra of ZnO quantum dots, which were observed in the range of 440-600 nm by bounding with 8-Anilinonaphthalene-1-sulfonic acid and/or lysozyme.…”

Nanostructured ZnO Materials: Synthesis, Properties and Applications

“…5.15). As hosting matrices, common polymers such as polymethylmethacrylate [229], polystyrene [230], poly(vinylalcohol) [231], and epoxy resins [232,233] as well as specialty polymers such as polynorbornene [234], polyacrylamide [235], polydiacetylene [236], and MEh-PPV copolymers [237] were used. A recent review of hybrid organic-inorganic light-emitting devices was reported by Sessolo and Bolink [238].…”
