Reaction chemistry/optical property relations : the special case of metal phosphides

F. Delpech

The synthesis of colloidal semiconductor nanocrystals has been under investigation for more than 30 years. A high degree of size and shape control has been achieved with selected material−shape combinations (e.g. II-VI and IV-VI materials). CdSe is the prime example of these achievements with the preparation of size-controlled 0D, 1D, 2D and 3D nanostructures with controlled optical properties. The case of metal phosphides and in particular of indium phosphide is in strong contrast. Indeed, advances in terms of morphological control and thus, in terms in optical properties lie far behind. A major blocking point is the growth inhibition of InP quantum dots which restricts the range of attainable emission wavelength. The lecture will focus on the hidden side of the reaction chemistry to semiconductor nanocrystals and the possible way to overcome the existing barriers in metal phosphide QDs synthesis.
