概要
- 論文の詳細を見る
Absorption intensities of two exciton bands in CuCl-CuBr solid solutions, the Z_<1,2> and Z_3, due to the spin-orbit splitting have been measured. In CuBr the Z_<1,2> band has a larger intensity than of the Z_3 but with increasing the Cl-doping the difference in intensities of two bands becomes small and in a solution Cu(Br_<0.23>Cl_<0.77>), where the spin-orbit splitting is zero, the Z_<1,2> band becomes very weak compared with the Z_3. The intensity variations of exciton bands are explained well by the theory of exchange interaction of Onodera and Toyozawa. The CuCl-CuBr system is found to be a suitable example where the effect of the exchange interaction appears remarkably.
