Exposed to spectral and uniform light, a one-dimensional, conducting and radiatively participating medium due to embedded absorbing and scattering gold nanoshells is solved. P1 Approximation method is used to solve the radiative transfer equation and finite difference explicit method is used to find the temperature distribution having both boundaries subjected to convection. The host medium was transparent to spectral radiation and the temperature distribution is obtained when the temperature of the irradiated boundary reaches the desired temperature such that any temperature in the medium does not exceed the melting temperature of the host medium. Variation of the concentration and configuration of gold nanoshells are found to change the radiative transfer spectrum that leads to an alteration in the local heat generation spectrum and the desired temperature distribution.
