Abstract

Colloidal suspensions of InP quantum dots (diameters 25 and 35 Å) show steplike absorption spectra which are blue-shifted by about 1 eV with respect to bulk material. Time resolved femtosecond spectroscopy at room temperature identifies the first quantum confined state. The nonlinear bleaching signal rises within 300 fs and persists longer than 200 ps.
