Cell Lab 4N (99.99%) Zinc Sulfide (ZnS) Pieces Evaporation Materials

Cell Lab 4N (99.99%) Zinc Sulfide (ZnS) Pieces Evaporation Materials [3–12 mm]

High-Purity ZnS for Optical Coating and Semiconductor Applications

General Description

Cell Lab 4N (99.99%) Zinc Sulfide (ZnS) Pieces are premium-grade evaporation materials engineered for optical coating, semiconductor, and thin-film applications. Owing to its wide band gap and high exciton binding energy, ZnS is a preferred choice for visible and infrared optical coatings, as well as for pigment and photocatalyst production.
With a high vapour pressure at relatively low temperature, ZnS evaporates cleanly under vacuum, forming films with excellent transparency and dielectric stability—ideal for manufacturing lenses, filters, and photovoltaic devices.

Key Features

• High Purity (99.99%) – Ensures superior optical clarity and consistent thin-film quality.

• Wide Band Gap Semiconductor – Enables efficient light transmission and high thermal stability.

• Excellent Film Uniformity – Provides stable refractive properties in both visible and IR regions.

• Optimised for Vacuum Evaporation – Low-temperature vapourisation minimises contamination risk.

• Customisable Dimensions – Available in standard 3–12 mm sizes; tailored sizes available upon request.

Technical Specifications

Applications & Industries

• Optical Coatings – For visible and infrared lenses, mirrors, and windows.

• Semiconductors – Used as a wide-bandgap material in advanced electronics.

• Photovoltaics – Thin-film solar cell and photodetector fabrication.

• Pigment & Catalysis – As a white pigment and photocatalytic support in chemical processes.

FAQ

Q1: Why is ZnS suitable for optical and semiconductor coatings?
Because of its high refractive index, wide band gap, and stable optical properties across visible and infrared wavelengths, ZnS is widely used in coating and photonic industries.

Q2: What precautions should be taken during evaporation?
ZnS has high vapour pressure even at moderate temperatures; evaporation should be performed in a properly sealed vacuum chamber to prevent contamination.

Q3: Can the material be used for E-beam deposition?
Yes, ZnS shows good compatibility with E-beam evaporation systems, using Mo or Ta boats for optimal stability.

Q4: Is custom sizing available?
Yes, Cell Lab offers size customisation between 3–12 mm or larger upon request, with bulk options for industrial use.
