Description of ZnS Zinc Sulfide 99.99% Pure Sputtering Target

Our ZnS Zinc Sulfide 99.99% Pure Sputtering Target addresses common issues in optical thin-film deposition. Lower-grade ZnS targets often suffer from sulfur loss and inconsistent microstructure during sputtering, causing uneven optical transmission and particle defects that ruin your test samples. We use high-purity raw powder and precisely controlled sintering to preserve accurate ZnS stoichiometry. The dense, homogeneous bulk reduces sulfur escape and particle generation, ideal for infrared optical coatings, optical windows, and optoelectronic research. Every target passes composition and microstructure inspection before shipment. Standard sizes are available, with backing plate bonding offered for stable chamber operation. Custom shapes and dimensions can be produced to match your sputtering equipment. Minimize wasted substrates caused by unreliable film quality, letting you focus on collecting consistent optical measurement data for your research projects.

Key Features of ZnS Zinc Sulfide 99.99% Pure Sputtering Target

Optical performance: High refractive index (about 2.35), wide bandgap (about 3.6 eV), high transmittance in the ultraviolet to infrared band (especially 8-12 μ m), making it an ideal material for infrared windows, laser components, and optical coatings.

Chemical stability: insoluble in water and ethanol, soluble in dilute acid; It will slowly oxidize into sulfate in the air and needs to be stored in a dry and sealed manner.

Crystal structure: There are two crystal forms, cubic sphalerite and hexagonal wurtzite, with a crystal transition temperature of about 1020 ℃.

Applications of ZnS Zinc Sulfide 99.99% Pure Sputtering Target

Optical coating: used for coating processes such as anti-reflective films, filters, infrared films, laser windows, etc.

Thin film solar cells: can be used as a buffer layer material for CIGS solar cells, which is more environmentally friendly compared to traditional CdS buffer layers, and has a wider bandgap and better transparency.

Semiconductor and Micro Nano Processing: Suitable for magnetron sputtering equipment, used in scientific research experiments, device manufacturing, semiconductor chips, flat displays, and special coatings. ‌‌

Procurement and Usage Suggestions

Purity confirmation: 99.99% refers to a very low total amount of metal-based impurities. When purchasing, it is recommended to request third-party testing reports (such as SGS, CNAS), with a focus on verifying impurity peaks such as Na, K, Ca, Si, etc., to prevent industrial grade (99.5%) from impersonating high-purity grade.

Packaging and storage: High-purity zinc sulfide is prone to moisture absorption and oxidation. Qualified products are usually packaged in vacuum bags with argon gas filling. They should be kept away from light, moisture, and sealed. Clean gloves should be worn during operation to avoid direct contact.
