Chalcogenides
Chalcogenides are compounds containing at least one chalcogen elemental ion and at least one metallic element. They typically include sulfides, selenides, and tellurides. Available in amorphous, crystalline, and nanocrystalline forms, chalcogenides are noted for their superior electronic, optical, and semiconducting properties. Additional distinctive features include an ability to bend, self-organize, and photo-darken. Whether your research focuses on sensors, optoelectronics, photovoltaics, or biomedical applications, we offer various low to high-purity compounds to optimally fit your needs.
Our Life Science Nanomaterials Research and Development Team is focused on providing you with materials at the forefront of innovation. In conformity with this focus, we offer diverse and exclusive chalcogenides, scaling and commercialization services, and customized solutions for diverse applications.

Transition Metal Chalcogenides and Dichalcogenides
Transition metal chalcogenides are ultra-thin materials with tunable electronic and optoelectronic properties, indirect bandgaps, and enhanced stabilities. While transition metal monochalcogenides are semiconductors of the type MX, dichalcogenides are of the type MX2 in which M is a transition metal and X is a chalcogen atom. These materials have an electronic bandgap making them useful for a wide range of applications in batteries, solar cells, flexible electronics, fiber optics, energy storage, and catalysis. We offer graphene-like transition metal dichalcogenides, such as molybdenum disulfide (MoS2) and tungsten disulfide (WS2), for utilization in field-effect transistors and monolayered photoluminescent thin films.
Chalcogenide Quantum Dots
Chalcogenide quantum dots are semiconductor nanoparticles with excellent quantum confinement effects, surface-volume ratio, solubility, edge effects, tunable photoluminescence, and fluorescence properties. We offer high-quality molybdenum disulfide (MoS2) and tungsten disulfide (WS2) quantum dots featuring easy functionalization and enhanced photostability. These materials impart a new dimension to standard 2D nanosheets, enabling applications in energy, batteries, and imaging.
