摘要：

For a system of coplanar electrons and holes the photoluminescence spectrum in the fractional quantum Hall regime does not exhibit anomalies associated with the fractional quantum Hall effect. However, when electron and hole layers are separated a new peak in the photoluminescence spectrum is introduced when the filling factor exceeds a fraction v0 at which an incompressible state occurs. The new peak is separated from the main spectral feature by the quasiparticle-quasihole gap and corresponds to a process in which a fractionally charged quasiparticle recombines with a hole leaving behind fractionally charged quasiholes.
