Abstract
The photoluminescence spectrum of quantized Hall states near filling factor ν=1 is investigated theoretically. For ν⩾1 the spectrum consists of a right-circularly polarized (RCP) line and a left-circularly polarized (LCP) line, whose mean energy (i) does not depend on the electron g factor for spin- quasielectrons; (ii) does depend on g for charged spin-texture excitations (Skyrmions). For ν<1 the spectrum consists of a LCP line shifted down in energy from the LCP line at ν⩾1. The g-factor dependence of the redshift of the LCP line determines the nature of the negatively charged excitations.
