The Energy Transfer Process under the Photonic Band Gap Modulation in Light Emitting Materials
Photonic crystal materials (PCs) are the new research fields of materials in the recent years. Because of its features of photonic localization and photonic band gap (PBG)
the photonic crystals changed traditional physical processes in it
and some new features and phenomena occur. The energy transfer in the photonic crystals is also affected. Through the research of energy transfer in PCs
a theory basis of this process will be established to guide the preparation experiments of luminous materials based on the PCs.<p/>In this paper
a kind of semi-classical theory was proposed based on the theory of photonic crystals and energy transfer in solid state to explain and analyze the process of energy transfer in 1-D PBG. A method to solve the similar problems was also generalized. We found out that the resonance dipole-dipole interaction (RDDI) plays a major role in the energy transfer. Effects of the photonic band gap modulation are reflected on the dispersion relation. So the dispersion relation can be introduced into the calculation of transition matrix. The related factors and mechanisms of the discussion about the energy transfer in PCs are concluded
finaly.
