%X The amorphous nanoclusters have short range order and long range disorder structures ordinarily. The radiation spectrum characteristics of an amorphous ZnO nanocluster are studied by using finite difference time domain method and the radiation spectrum shows as spontaneous emission. To control the spontaneous emission, photonic crystal is introduced to lead the radiation emission to the needed frequency. An easier and cheaper manufacture method is put forward in which the nanocluster should be inserted between two colloidal crystal films which self-assembled by uniform colloidal nanoparticles. According to this idea, a two dimensional system is constructed and the radiation characteristics of this system are simulated. The results show that the energy is controlled in this system effectively. This scheme can provide a new way to manufacture low threshold micro-lasers feasible for imbedding in optical integrated circuits.
