PHOTOLUMINESCENCE SIGNATURE OF SKYRMIONS AT NU=1

The photoluminescence spectrum of quantized Hall states near filling f actor v=1 is investigated theoretically. For v greater than or equal t o 1 the spectrum consists of a right-circularly polarized (RCP) line a nd a left-circularly polarized (LCP) line, whose mean energy (i) does not depend on the electron g factor for spin-1/2 quasielectrons; (ii) does depend on g for charged spin-texture excitations (Skyrmions). For v<1 the spectrum consists of a LCP Line shifted down in energy from t he LCP line at v greater than or equal to 1. The g-factor dependence o f the redshift of the LCP Line determines the nature of the negatively charged excitations.
