We note from the further studies that in the crystals, which sharing the similar crystal structures and coordinational environments, the magnitude of the Stokes shift of the luminescence of the dopant ion is in line with the average covalency of the replaced lattice site. This is because that the nature of Stokes shift is the energy transfer from the luminescent ion to the host lattice. The value of this energy is determined by the frequency of the host lattice in which the frequency is controlled by the chemical bond characters.

更深入的研究发现，在晶体结构和中心离子配位环境非常相似的系列晶体中，掺杂离子发射光的Stokes位移值与其所取代格位的平均共价性成正比的关系，这是由于Stokes位移的本质是发光离子在发光过程中向基质以光波辐射的形式传递能量，这一能量的大小是由基质的振动频率决定的，而基质的化学键性质恰恰决定着基质的振动频率。
