Perovskite Quantum Dots Supplier - Alfa Chemistry

Custom Lead-free Composite Perovskites Quantum Dots


Alfa Chemistry is an innovator and manufacturer of perovskite quantum dot materials in the industry. Alfa Chemistry meets the market demand for inorganic perovskite quantum dots, organic-inorganic perovskite quantum dots, lead-free perovskite quantum dots and perovskite materials. We use advanced technology and strict quality specifications to meet customer needs.

Custom lead-free composite perovskite quantum dots


Among perovskite quantum dots, lead-based perovskite quantum dots are the most fully studied. They stand out among all kinds of optoelectronic materials. Mainly due to the high light absorption coefficient, narrow emission spectrum, high quantum yield and adjustable emission spectrum of this kind of material. It is currently widely used in light-emitting diodes, lasers, solar cells and photodetectors, etc. field. However, lead-based perovskite quantum dots have several important problems: (1) The toxicity of lead. Lead pollution has a great impact on the environment and cannot be used in experiments such as biological testing, which is inconsistent with the current concept of environmentally friendly sustainable development; (2) Lead-based perovskites have poor stability and are easily decomposed or agglomerated in polar solvents, it is very sensitive to light, heat and humid environment. The lead-free perovskite quantum dot service can well solve some of the above-mentioned problems. The stability of lead-free perovskite quantum dots is better than that of lead-based perovskite quantum dots, and it is non-toxic and environmentally friendly.


Alfa Chemistry provides lead-free perovskite quantum dots are meticulously designed and manufactured to provide suitable products and services for all sample types associated with solar cells, light-emitting diodes, lasing and photodetectors. All our products are backed by top-notch customer service and support. Our custom lead-free composite perovskite quantum dot services including:
