Devices And Other Fields Zinc Oxide
Zinc Oxide
Physical properties: Zinc oxide (nanoscale) is usually in the form
of white powder with high chemical and thermal stability. It is
odorless at room temperature and has good optical and electrical
properties.
Structure: The crystal structure of zinc oxide is a hexagonal
close-packed structure, in which zinc ions and oxygen ions are
arranged in the lattice in the form of plasma. The crystal size of
nanoscale zinc oxide is usually between 1 and 100 nanometers, with
a large specific surface area and excellent photoelectric
properties.
Optical properties: Zinc oxide has a high refractive index and
transparency in the visible and ultraviolet regions. It exhibits
excellent ultraviolet absorption and fluorescence emission
characteristics, so it is widely used in ultraviolet absorbers,
fluorescent materials, optoelectronic devices and other fields.
Electrical properties: Zinc oxide is a semiconductor material with
high electrical conductivity and electron mobility. It has
important applications in optoelectronic devices (such as solar
cells), sensors, transparent conductive films, etc.
Antibacterial properties: Zinc oxide has good antibacterial
properties and has inhibitory effects on a variety of bacteria and
fungi. This makes zinc oxide widely used in antibacterial products
and materials in the fields of medical care, cosmetics, textiles,
etc.
Catalytic performance: Zinc oxide also has certain applications in
the field of catalysis. The high specific surface area and active
surface of nano-scale zinc oxide can improve the efficiency and
selectivity of catalytic reactions, such as in photocatalysis,
catalyst carriers, etc.
Application fields: The application of zinc oxide (nanoscale) is
very extensive. It is widely used in solar cells, display devices,
light-emitting diodes (LEDs), blue light emitting materials, rubber
additives, ceramic materials, sunscreens, skin care products,
coatings, plastics, rubber products, preservatives and other
fields.

Preparation methods and common applications of zinc oxide
Zinc oxide can be prepared by a variety of methods, including
calcination, hydrothermal, sol-gel and solution methods. Each
method has its own characteristics and scope of application, and
the appropriate preparation method can be selected according to
specific needs. The calcination method is suitable for large-scale
industrial production, while the sol-gel method can obtain zinc
oxide powder with smaller particles and uniform distribution. The
application of zinc oxide in the fields of environmental protection
and new energy is also becoming more and more extensive, such as
photocatalytic degradation of organic matter, solar cells, etc.
With the advancement of science and technology and people's pursuit
of high-quality life, the application scope of zinc oxide will
continue to expand, and its importance will become increasingly
prominent. In the future, through continuous research and
innovation, zinc oxide is expected to create a better living and
working environment for us.

Theory
Zinc oxide belongs to the N-type semiconductor category, exhibiting
excellent luminescent properties at room temperature. It has a
large energy band gap and exciton binding energy, resulting in high
transparency. The principle of zinc oxide absorbing UV radiation is
that electrons in the valence band can absorb energy from UV
radiation and undergo transitions. The function of scattering UV
radiation is related to the particle size of the material, with
nanoscale particles offering significant advantages.
