Abstract
The optical properties of the a-plane oriented ZnO described by an inhomogeneous model are investigated by using another form of Gaussian function. The reflectivity spectrum of the excitons A, B and C are represented by using the same physical parameters than the theory of the spatial resonance dispersion of Hopfield model. The data obtained are well discussed and are, as well, almost the same than the experimental data found by the authors.
