Chalcogenides denote compounds encompassing at least one chalcogen elemental ion and one metallic element, typically encompassing sulfides, selenides, and tellurides. Exhibiting amorphous, crystalline, and nanocrystalline structures, chalcogenides are renowned for their exceptional electronic, optical, and semiconducting properties. Notably, they possess the capability to flex, self-organize, and undergo photo-darkening. Whether your research revolves around sensors, optoelectronics, photovoltaics, or biomedical applications, our array of compounds, ranging from low to high purity, is tailored to optimally suit your requirements.

Our Life Science Nanomaterials Research and Development Team is devoted to furnishing you with cutting-edge materials. In alignment with this dedication, we provide a diverse assortment of exclusive chalcogenides, along with scaling and commercialization services, as well as personalized solutions across a spectrum of applications.

Transition Metal Chalcogenides and Dichalcogenides:

Transition metal chalcogenides represent ultrathin materials, characterized by modifiable electronic and optoelectronic properties, indirect bandgaps, and enhanced stability. Among these, transition metal monochalcogenides adopt the MX configuration, functioning as semiconductors, while dichalcogenides adhere to the MX2 format, where M signifies a transition metal and X denotes a chalcogen atom. Notably, these materials possess an electronic bandgap, rendering them valuable in diverse realms such as batteries, solar cells, flexible electronics, fiber optics, energy storage, and catalysis. We offer graphene-like transition metal dichalcogenides like molybdenum disulfide (MoS2) and tungsten disulfide (WS2), designed for applications in field-effect transistors and monolayer photoluminescent thin films.

Chalcogenide Quantum Dots:

Chalcogenide quantum dots embody semiconductor nanoparticles that manifest remarkable quantum confinement effects, surface-volume ratio, solubility, edge effects, tunable photoluminescence, and fluorescence attributes. Our selection features high-quality molybdenum disulfide (MoS2) and tungsten disulfide (WS2) quantum dots, designed for easy functionalization and augmented photostability. These materials introduce a new dimension to standard 2D nanosheets, thereby enabling innovative applications spanning energy, batteries, and imaging.
