Products Description
Selenium targets are materials made of high-purity selenium, usually between 4N and 6N, and are mainly used for sputtering coatings. They have good electrical and thermal conductivity and are mainly used in electronics, optics, solar energy and other fields.
Our selenium sputtering targets have good electrical and thermal conductivity and can provide stable performance under high temperature and high pressure environments.
They also have strong chemical stability and corrosion resistance, so they can maintain a long service life in extreme environments. Especially in the production of solar cells, selenium sputtering targets help improve the photoelectric conversion efficiency through their excellent light absorption characteristics.

Common types
Pure selenium target: used to prepare intrinsic selenium thin films (such as X-ray detectors)
Alloy targets: such as Se-Te (phase change storage materials), Se-As (infrared optical glass)
Compound targets: such as cadmium selenide (CdSe, photovoltaic materials), antimony selenide (Sb₂Se₃, light absorption layer)
Process
Purification of high-purity selenium:
Vacuum distillation method to remove impurities such as sulfur and tellurium
Regional melting method to further improve purity
Forming and processing:
Melting casting or hot pressing sintering (avoid high-temperature oxidation)
Mechanical processing into thin targets (thickness 3-10 mm)
Storage: Need to avoid light, vacuum or inert gas protection (selenium is easy to volatilize and oxidize)
Main applications
(1) Photodetectors
X-ray/γ-ray detection: amorphous selenium (α-Se) thin films are used for medical imaging (such as DR flat panel detectors)
Visible light sensors: the photosensitivity of selenium thin films can be used for photoconductive devices
(2) Solar cells
Antimony selenide (Sb₂Se₃) thin film cells: low-cost, high-efficiency (>10%) photovoltaic materials
CIGS (copper indium gallium selenide) cells: selenium as a key component to improve light absorption efficiency
(3) Phase change memory (PCM)
Se-Te alloys: used for reversible phase change storage materials (crystalline ↔ amorphous resistance switching)
(4) Glass and optical coatings
Arsenic selenide (As₂Se₃): used for infrared lenses and optical fiber materials
