Indium selenide (InSe) powder is a high-performance III-VI semiconductor material with a layered crystal structure. Its combination of excellent optoelectronic properties, thermal stability, and tunable bandgap makes it a highly promising material for optoelectronics, photovoltaics, infrared detectors, and thermoelectric devices.
We offers high-purity InSe powder with a purity of 99.99% (4N) and customizable particle sizes from nanometers to micrometers. It can be further processed into sputtering targets, evaporation sources, and two-dimensional crystalline materials.
Optoelectronic Devices: Used in photodetectors, photoconductive devices, and optical communication components.
Photovoltaic Applications: Used as an absorber material in thin-film solar cells.
Infrared and Thermoelectric Devices: Used in infrared detection, thermoelectric conversion, and energy recovery.
Two-Dimensional Materials and Frontier Research: Preparation of single-layer or few-layer InSe for flexible electronics, quantum devices, and novel semiconductor research.
High purity (99.99%), customizable – ensuring superior electrical and optical properties
Customized particle size – from nanometers to micrometers
Reliable batch consistency – strict impurity control and quality testing
Flexible supply options – suitable for R&D and industrial production
Secure packaging and global shipping – vacuum-sealed with inert gas
Q1: How do you package and ship InSe powder?
A1: Our InSe powder is vacuum-sealed in anti-static aluminum foil bags or bottles filled with inert gas to ensure safe international shipping.
Q2: What are the recommended storage conditions?
A2: InSe powder should be stored in a cool, dry place under an inert gas atmosphere. Avoid exposure to light, moisture, and air to prevent oxidation.
Q3: Can you provide custom particle sizes or bulk supply?
A3: Yes, we offer nano- and micro-sized indium selenide powders, supporting both small-scale R&D and large-scale industrial production.
Q4: What documents and certificates can you provide?
A4: We provide COA, TDS, MSDS, and impurity analysis reports to ensure full product transparency and traceability.
We can provide Certificates of Analysis (COA), Technical Data Sheets (TDS), Material Safety Data Sheets (MSDS), and ICP-MS impurity analysis reports upon request. We can also prepare samples for third-party testing upon request and provide shipping test reports.
