We have study the phenomenon on of phase transition in photonic band gap (PBG) materials doped with four-level nanoparticles in the presence of the dipole-dipole interaction. Numerical simulations for the real susceptibility have been performed for an isotropic PBG material. It is found that the real susceptibility has a singularity for a certain value of the nanostructure concentration. This is a signature of the phase transition in the system.
