The Yukawa screening potential is modified to describe the effect of enviroment on energy of exciton in monolayer semiconductor WS2. The FK Operator Method combined with Laplace transformation is used to retrieve the energies for the states of n= 1, 2, 3 which are coincident with experimental data. Experimental values of the parameters in the screening potential expression are also obtained for further use in the case of presence of external field.
