Synthesis and characterization of cadmium selenide and zinc selenide nanoparticles
… The synthesis involved the reduction of selenium powder to produce selenium ions. The complete reduction of selenium is followed by the addition of a metal source MX (M = Cd or Zn and X = Cl or CO). Biocompatible passivating agents such as cysteine or triethanolamine (TEA) induced the …

Heavy-metal-free colloidal nanocrystal heterostructures – synthetic chemistry and growth mechanisms
… for ZnTe-based nanocrystals. The highly reactive selenium powder provides better synthetic control of the ZnSe shell. In addition, highly reductive ligand (diphenylphosphine) can further increase the PL QY presumably by filling surface electron trap states.
