Introduction
Nickel oxide (NiO) is formed from nickel and oxygen. It is known for its semiconductor properties and wide-ranging applications in material science. NiO is used in various thin film deposition processes as a sputtering target, where ions bombard the target, ejecting atoms to form thin films on substrates. These films have essential characteristics such as electrical conductivity, chemical stability, and optical properties, making NiO a versatile material in electronics, sensors, and energy storage.

Applications
Nickel oxide has many applications, including:
- Thin-film transistors (TFTs): These are used to produce semiconductors for electronics.
- Electrochromic devices: NiO thin films are used in bright windows and displays that change color when an electrical voltage is applied.
- Gas sensors: Nickel oxide films are sensitive to carbon monoxide and hydrogen, making them useful in gas detection devices.
- Batteries and supercapacitors: NiO is an anode material in energy storage devices, including lithium-ion batteries. NiO is a typical hole transport material in thin-film solar cells.
- Optoelectronic devices: These are employed in sensors, solar cells, and displays due to their optical properties.
- Magnetic materials: Due to its ferromagnetic properties, NiO is used to create thin films for magnetic storage and sensors.
- Transparent electrodes: Gold-doped nickel oxide films can be employed as transparent electrodes in optoelectronic devices, resulting in nickel cermet for solid oxide fuel cell anode layers.
FAQs
Answere: Nickel oxide powders are an electrolyte in nickel-plating solutions and an oxygen donor in auto-emission catalysts. They can also anodize aluminum, conductive nickel zinc ferrites, glass frit for porcelain enamel, thermistors, cermet, and resistance heating elements.
Answere: Nickel resists corrosion and protects other metals through plating. Manufacturers mainly use it to make alloys like stainless steel. Nichrome, a nickel-chromium alloy, contains trace amounts of silicon, manganese, and iron.
Answere: NiO nanoparticles are used in various applications, including battery electrodes, photo-electron devices, ion storage materials, gas sensors, magnetic materials, thermoelectric materials, catalysts, fuel cells, dye-sensitized photocathodes, and electrochromic films.
Answere: Chronic exposure to this chemical may cause lung and nasal cancer. It may also result in sinus and laryngeal carcinoma. Nickel oxide may be light-sensitive. It should remain thermally stable at temperatures of up to 644°F.
Answere: Nickel (II) oxide is a chemical compound with the formula NiO, where nickel oxide is the main component. NiO is a necessary metal oxide. NiO's mineralogical form, bunsenite, is intermittent. NiO follows the NaCl structure, having octahedral Ni2+ and O2− sites.
