Zinc oxide nanoparticles are nanoparticles of zinc oxide (ZnO) that have diameters less than 100 nanometers. They have a large surface area relative to their size and high catalytic activity . The exact physical and chemical properties of zinc oxide nanoparticles depend on the different ways they are synthesized .
Copper zinc tin sulfide (CZTS) is a quaternary semiconducting compound which has received increasing interest since the late 2000s for applications in thin film solar cells. The class of related materials includes other I 2 -II-IV-VI 4 such as copper zinc tin selenide (CZTSe) and the sulfur-selenium alloy CZTSSe.
To directly create ZnO nanostructures, one can decompose zinc oxide at high temperatures where it splits into zinc and oxygen ions and when cooled it forms various nanostructures, including complex structures such as nanobelts and nanorings. [5] Alternatively, zinc powder can be transported through oxygen vapor which react to form nanostructures .
The breakthrough material ZIF-8, composed of zinc ions and 2-methylimidazolate linkers, exemplifies the unique properties of ZIFs. ZIF-8 demonstrated exceptional chemical and thermal stability, coupled with a highly selective pore system, making it suitable for demanding applications like carbon dioxide capture and hydrocarbon separation.

Upconverting nanoparticles (UCNPs) are nanoscale particles (diameter 1–100 nm) that exhibit photon upconversion. In photon upconversion, two or more incident photons of relatively low energy are absorbed and converted into one emitted photon with higher energy.
Zinc oxide is an inorganic compound with the formula Zn O.It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, [12] paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors ...
The characterization of nanoparticles is a branch of nanometrology that deals with the characterization, or measurement, of the physical and chemical properties of nanoparticles.,. [1] Nanoparticles measure less than 100 nanometers in at least one of their external dimensions, and are often engineered for their unique properties. Nanoparticles ...
Zinc telluride together with lithium niobate is often used for generation of pulsed terahertz radiation in time-domain terahertz spectroscopy and terahertz imaging.When a crystal of such material is subjected to a high-intensity light pulse of subpicosecond duration, it emits a pulse of terahertz frequency through a nonlinear optical process called optical rectification.
