中文摘要	spontaneous emission from gaas/algaas quantum dots (qds) embedded in photonic crystals with a narrow photonic band gap is studied theoretically. the results show that the decay lifetime is very sensitive to the sizes of qds, and both inhibited and accelerated emission can occur, which had been indicated in a previous experiment. the weisskopf-wigner approximation, good for atoms and molecules, may be incorrect for qds. a damped rabi oscillation of the excited state with the transition frequency outside the photonic band gap may appear, which is impossible for atoms and molecules.
