    Abstract

    We present a microscopic quantum theory of spatially resolved photoluminescence in quantum wells with interface fluctuations that includes light quantization, acustic phonon scattering, and inhomogeneous sample-excitation and/or light-detection. The theory can model low-temperature photoluminescence and photoluminescence excitation experiments performed in illumination, collection or illumination-collection mode or diffusion experiments where the spatial positions of excitation and collection are scanned independently. Numerically calculated two-dimensional images agree with images from near-field photoluminescence experiments and put forward the potentials of the method for the understanding of near-field light emission from semiconductor quantum structures.
