N2 - Kinetics of polarized photoluminescence (PL) of the InPquantum dots with variable number of resident electrons is studied. Along-lived component of the degree of circular polarisation of the PL isfound to be present for charged quantum dots and absent for neutral ones.Behaviour of the long-lived polarisation in longitudinal and transversemagnetic field is studied. Experimental data obtained allowed us toconclude that the long-lived polarisation is related to spin orientation inthe quantum dots containing odd number of carriers. We found that theirreversible spin relaxation time in these dots substantially exceeds 1 ns.
