Zinc oxide is an inorganic compound with the formula Zn O.ZnO is a white powder that is insoluble in water. It is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and first-aid tapes. Upon modifying cadmium-free InP quantum dot emitting layer by passivation with 1,4-butanediamine and zinc iodide, we successfully decrease electron mobility and enhances the hole transport in the InP QLED. As a result of optimizing the electrons and hole injection, it leads to green 545 nm InP QLED with a maximum quantum efficiency (EQE) of 16.3% and a current efficiency of 57.5 cd/A.

The use of nanofibers creates the ability for non-enzymatic sensing in various applications and greatly improves the sensitivity, speed, and accuracy of electrochemical sensors for a wide variety of analytes. The high surface area to volume ratio of the fibers as well as their high porosity, even when compared to other common nanostructures, allows for enhanced electrocatalytic, adsorptive ...
