AgI，CuI，CuBr，和CuCl的激子光谱进行了讨论和各种峰归因于几个共存的晶体修改。的位移与合金的浓度与这些化合物形成的伪二元系统的峰的报告和解释。这些材料和它们的合金的吸收和反射光谱的能量之间的能隙和10 eV的报告和结构归因于区域之间的过渡的价带低于最高的最大值和部分的导带高于最低的最小值。这些光谱与其他闪锌矿和纤锌矿类材料的相应光谱进行了比较。
The exciton spectrum of AgI, CuI, CuBr, and CuCl is discussed and various peaks attributed to several coexisting crystal modifications. The shift of the peaks with alloy concentration in the pseudobinary systems formed with these compounds is reported and interpreted. The absorption and reflection spectra of these materials and their alloys for energies between the energy gap and 10 eV is reported and the structure attributed to transitions between regions of the valence band lying below the highest maximum and parts of the conduction band higher than the lowest minimum. These spectra are compared with the corresponding spectra of other zincblende-and wurtzite-like materials.
