We study the effects of exciton-longitudinal optical phonon interaction on the exciton binding energies in ZnS/Mg_{x}Be_{y}Zn_{1-x-y}S single quantum wells. The heavy- and light-hole exciton binding energies increase to the exciton-logitudinal optical phonon interaction. The increase in the maximum heavy-hole (light-hole) exciton binding energy for x=0.74 is 68.3 meV (55.0 meV). In narrow ZnS/Mg_{x}Be_{y}Zn_{1-x-y}S single quantum wells SQWs, the heavy- and light-hole exciton binding energies exceed the longitudinal optical phonon energy of ZnS when x ≥ 0.1.
