The coherent control of the spontaneous emission spectrum of a driven atom located within photonic crystals with two atomic position-dependent bands is investigated. The driving laser field splits the excited atomic level into a doublet that is further dressed by two bands bonded together with the atomic position in the crystal unit cell. The spontaneous emission spectrum of the atomic transition in free space is discussed. We find that frequency shift and the intensity of the spectrum can be perfectly manipulated by variation of the atomic position and detuning of the laser field. The result perhaps offers us an interesting route towards tunable photonic devices.
