摘要:

The cathodoluminescence of AgGaS2, a I‐III‐VI2ternary chalcopyrite compound, has been studied in the 2.1–2.8‐eV range at 300, 77, and 21 °K. At 300 and 77 °K the annihilation of free excitons is observed, while at 21 °K only extrinsic transitions appear. A study of the polarization shows that the excitonic lines are polarizedE∥C.
