| contents | We show how to calculate the optical functions of a nanoplatelet, taking into account the effect of a dielectric confinement on excitonic states. Real density matrix approach is employed to obtain analytical and semi-analytical relations for the absorption coefficient, the exciton resonance energy and binding energy of nanoplatelets and nanodisks. The impact of plate geometry (thickness, area) on the spectrum is discussed and the results are compared with the available experimental data. |
