The temperature dependence of the effective nonlinear optical properties is investigated in the random metal/cermet films with a shape distribution of metal particles. We adopt the normal Maxwell-Garnett model and obtain an analytical expression for the spectral density function of two-component composites in which the metallic inclusions possess a shape distribution P(L) of geometric. Numerical results show that the optical nonlinearity enhancement dependence on the temperature and volume fraction of component, and accompanied by a slight blueshift of the resonant peak.
