Oxide Nanopowder

Cadmium oxide nanoparticles (CdO) as an important semiconductor has promising applications in catalysts, sensors, solar cells, and other optoelectronic devices. Cadmium is used industrially to plate other metals, in pigments, batteries, stabilizers for plastics, metallurgy, nuclear reactor rods, and semiconductors. Cadmium is deposited in soil and water near the industrial source.

Cadmium oxide nanoparticles (CdO): Due to their applications in several areas of research, specifically in optoelectronic and other applications, including solar cells, phototransistors, photodiodes, transparent electrodes and gas sensors.  Reduction in the dimensionality of such materials from the three-dimensional bulk phases to the zero-dimensional nanoparticles can lead to enhanced non-linearity, determined by the quantum size effects and other mesoscopic effects.

Cadmium oxide (CdO) nanoparticles cost significantly less than silver and gold; therefore, these are economically attractive. When cadmium nanoparticles are exposed to air, surface oxidation occurs and ultimately aggregation appears in a short time. Oxide nanomaterials applied as catalysts and starting materials for preparing highly developed structural ceramics.

Cadmium oxide nanoparticles are used as a transparent conductive material, which was prepared as a transparent conducting film. Cadmium oxide in the form of thin films has been used in applications such as photodiodes, phototransistors, photovoltaic cells, transparent electrodes, liquid crystal displays, IR detectors, and anti-reflection coatings.  CdO microparticles undergo bandgap excitation when exposed to UV-A light and are also selective in phenol photodegradation.

Cadmium oxide nanoparticles are used in cadmium plating baths, electrodes for storage batteries, cadmium salts, catalysts, ceramic glazes, phosphors, and nematocide. Major uses for cadmium oxide are as an ingredient for electroplating baths and in pigments. Cadmium is found primarily as cadmium sulfide in ores containing zinc, lead, and copper. Cadmium volatilizes more rapidly than other metals when the ore is being smelted, and it condenses to form fine airborne particles that react immediately with oxygen to form cadmium oxide fumes.
