研究了薄膜电致发光器件中的电子散射过程，计算了ＺｎＳ∶Ｍｎ２＋中声学声子、极化光学声子、电离杂质及谷间散射的几率随电子能量的变化关系，对各种散射过程进行了比较，发现极化光学声子散射及谷间散射较为重要，杂质散射的重要性取决于浓度的大小。同时研究了它们在不同能谷中的行为。进而研究了温度对散射过程的影响。 The scattering process of electrons in thin-film electroluminescent devices was studied. The relationship between the acoustic phonon, the polarized optical phonon, the ionized impurities and the probability of scattering in the valley with the electron energy in ZnS: Mn2 + was calculated. In comparison, it is found that the polarization phonon scattering and the intergranular scattering are more important. The importance of impurity scattering depends on the concentration. At the same time, they studied their behavior in different valleys. Then the effect of temperature on the scattering process is studied.
