In pulsed high magnetic fields up to 40 T perpendicular to layers, we investigated photoluminescence (PL) from quasizero-dimensional carriers in modulation-doped GaAs/A1GaAs quantum wells for various electron densities at 77 K. We observed an oscillation of PL intensity due to magnetophonon resonanc
