在4.2K下测量了ZnSe：Mn和CdS：Mn晶体的吸收光谱和发射光谱。在吸收和发射带的结构被确定在声子发射耦合到一个电子跃迁在每个频带。在ZnSe：Mn中发现了18 025、19 598和21 110 cm− 1的零声子线，在CdS：Mn中发现了18 620 cm− 1的零声子线。它们对应于ZnSe中立方晶场A16 → T14，A16 → T24和A16 → A14，E4中的Mn跃迁。离子参数F2 = 55 454和F4 = 34 520 cm-1和晶体场的值，Dq = 405 cm-1，推导出Mn在ZnSe中。参与的主要声子具有约70、94、160、209和242 cm− 1的值，这与ZnSe基质晶格的声子能量一致。
Absorption and emission spectra of ZnSe: Mn and of CdS: Mn crystals were measured at 4.2 K. The structure on the absorption and emission bands was identified in terms of phonon emission coupled to one electronic transition in each band. Zero-phonon lines were found in ZnSe: Mn at 18 025, 19 598, and 21 110 cm− 1 and in CdS: Mn at 18 620 cm− 1. They should correspond to the Mn transitions in a cubic crystalline field A 1 6→ T 1 4, A 1 6→ T 2 4, and A 1 6→ A 1 4, E 4 in ZnSe. The ionic parameters F 2= 55 454 and F 4= 34 520 cm− 1 and the value of the crystalline field, D q= 405 cm− 1, are deduced for Mn in ZnSe. Principal phonons participating have values of about 70, 94, 160, 209, and 242 cm− 1, which is in agreement with the phonon energies of the ZnSe host lattice.
