I. Outstanding Properties of nano AZO

1. Excellent Electrical Conductivity: After aluminum doping, the crystal structure of AZO undergoes subtle changes, significantly increasing the electron mobility. This enables AZO to possess good electrical conductivity while maintaining a certain degree of transparency. Its resistivity can be as low as the order of 10⁻⁴Ω·cm, giving it a distinct advantage in the field of transparent conductive materials.
2. High Transparency: In the visible light range, AZO nanoparticles have very low light absorption and scattering, achieving a light transmittance of over 85%. This property makes it an ideal choice for numerous applications that require transparency and electrical conductivity, such as transparent electrodes and display devices.
3. Good Chemical Stability: Zinc oxide itself has certain chemical stability, and the doping of aluminum further enhances the chemical inertness of AZO. It can remain stable in various chemical environments, being resistant to oxidation and corrosion. This provides a strong guarantee for its application in various complex environments.
4. Strong Ultraviolet Absorption Ability: AZO has a strong absorption effect on ultraviolet light, especially in the ultraviolet band of 200 – 400nm. This property gives it broad application prospects in fields such as sun protection and ultraviolet shielding, effectively protecting the human body and materials from ultraviolet damage.

II. Wide Applications of Nano AZO

1. Solar Cell Field: As a transparent conductive electrode material, Nano AZO can efficiently collect and transport photo – generated carriers, improving the photoelectric conversion efficiency of solar cells. Its good electrical conductivity and high transparency help reduce the internal resistance loss of the battery, enabling more light energy to be converted into electrical energy. Currently, many research teams are committed to optimizing the application of AZO in solar cells to promote the widespread use of solar energy, a clean energy source.
2. Display Technology Field: In display devices such as liquid crystal displays (LCDs), organic light – emitting diode displays (OLEDs), and touchscreens, AZO is widely used in the preparation of transparent conductive films. It can not only achieve clear and bright image display but also improve the touch sensitivity of the screen, bringing users a more smooth interactive experience. With the continuous development of display technology, the performance requirements for AZO materials are getting higher and higher, and related research and innovation are also ongoing.
3. Building Energy – Saving Field: Adding AZO nanoparticles to building glass or coatings can prepare intelligent building materials with functions such as heat insulation, thermal insulation, and ultraviolet protection. This material can effectively block the heat and ultraviolet rays in solar radiation from entering the room, reducing the air – conditioning energy consumption of buildings and providing a more comfortable and healthy indoor environment. In an era of advocating energy conservation and emission reduction, the application prospects of AZO in the construction field are very broad.
4. Other Fields: In addition to the above – mentioned main application fields, AZO also shows great application potential in sensors, catalyst carriers, antibacterial materials, etc. For example, the gas – sensitive sensor based on AZO has high sensitivity and fast response characteristics to various harmful gases and can be used for gas detection in environmental monitoring and industrial production. As a catalyst carrier, AZO can improve the activity and stability of the catalyst, playing an important role in fields such as chemical synthesis and environmental protection.
