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].…”

Photoluminescence properties of polymethyl methacrylate-coated Zn2SnO4 nanowires

“…In particular, in the case of ZnO one-dimensional nanostructures, encapsulation or capping techniques, using a variety of coating materials including metals [16][17][18][19][20], ceramics [21][22][23][24][25][26][27][28][29][30][31] and polymers [32,33], have been studied widely to enhance NBE emission. Poly-methyl methacrylate (PMMA) [32] and polyaniline have been evaluated as a polymer coating material [33].…”

“…Poly-methyl methacrylate (PMMA) [32] and polyaniline have been evaluated as a polymer coating material [33]. This study examined the effects of PMMA coating on the PL of Zn 2 SnO 4 nanowires.…”

Low-Current Focused Ion Beam Milling for Freestanding Nanomaterial Characterization

“…However, depending on the shape and the distribution of nanoobjects, the characterization of structural, compositional, and electrical properties may not be possible for some characterization techniques. Up to now, for the characterization of the properties of nanomaterials, the most popular method has been to use a blade to scratch the support substrate and release the nanomaterials, sonicate in ethanol for dispersion, and then transfer to either a transmission electron microscope grid for structural and compositional analysis [ 13 ] or a substrate covered with a layer of dielectric material such as SiO 2 for characterization of electrical and optical properties [ 14 ]. However, the scratch-pick-dispersion-transfer technique has some disadvantages, which include the following: (1) mechanical damage of the original shape of the target, especially for limbed and complex nanostructures; (2) it is time-consuming for contact fabrication; (3) it is extremely diffi cult, even impossible, to fi nd the target after scratching.…”
