单一原子 (分子 )的自发辐射衰变的动力学性质强烈地依赖于其在光子晶体中的位置及其辐射偶极矩与所处位置场的相对方向 .测量单一原子 (分子 )的自发辐射衰变特性只能反映光子晶体的局域态密度特征 ,而不能反映光子晶体的全态密度特征 .理论上研究发现 ,通过引入含不同密度分布的发光分子可以探测到光子晶体的全态密度的部分细节甚至全部信息 .按来源首次将全态密度分为两个部分 ,证明了特定的发光分子分布可以完善地反映其中的一部分或者全部 ,这为解释、设计加速或抑制原子 (分子 )自发辐射的实验提供了有益的指导 .
The dynamics of the spontaneous emission decay of a single atom (molecule) strongly depends on its position in the photonic crystal and the relative orientation of its radiation dipole moment to the location field at which it is located.Detecting the spontaneous emission decay behavior of a single atom (molecule) Can only reflect the local density of states of photonic crystals, but can not reflect the full density of photonic crystals.Research shows that the introduction of different density distribution of luminescent molecules can detect some details of the total density of photonic crystals or even All information. For the first time, the total state density is divided into two parts by source, demonstrating that a specific luminescent molecule distribution can perfectly reflect some or all of this, providing an experiment to explain, design and accelerate or inhibit the spontaneous emission of atoms (molecules) Helpful guide
