Perovskite Quantum Dots Supplier - Alfa Chemistry

Custom Lead-free Perovskite Quantum Dots


Lead-free perovskite quantum dots can reduce the toxic lead ion content and can be used to study new luminescence phenomena. Alfa Chemistry is always at the forefront of advanced technology, which can focus on the latest problems of quantum dots and carry out analysis and research according to specific conditions, so as to apply optimized product solutions to products.

Lead-free perovskite quantum dots replace lead ions in perovskite quantum dots by doping other metal ions (Sn, Zn, Cd, Mn, etc.), on the one hand to explore new luminescence phenomenon, on the other hand to reduce the content of toxic lead ions. The luminescence efficiency was adjusted by adjusting the quantum dot size and anion composition. The picture below shows the new lead-free perovskite quantum dots replaced by other elements.
