J&K Scientific offers a comprehensive selection of quantum dot synthesis reagents for the controlled preparation, surface modification, and functionalization of semiconductor nanocrystals. The portfolio includes high-purity metal precursors, chalcogen sources, surface ligands, capping agents, high-boiling solvents, and shell-growth materials for systems such as CdSe, CdS, CdTe, InP, and perovskite quantum dots. These reagents support key synthesis methods including hot-injection, nucleation and growth, ligand exchange, and core–shell quantum dot preparation, helping researchers achieve consistent particle size, optical properties, colloidal stability, and surface performance. Suitable for research and advanced materials development in QLED displays, photovoltaics, bioimaging, photodetectors, and sensing applications.
