Abstract
A new experimental method is presented to determine the sign of the electron Land' g factor in semiconductors by time-resolved magneto photoluminescence. This technique is used to demonstrate the reversal of the electron g factor for different material compositions. Measurements and theoretical estimates for the spin dynamics in quantum well systems are compared.
