Abstract
AbstractThe 4T1(F) → 4A2(F) transition of Co2+ (d7) ions in ZnSe is detected by its emission at T ≈︁ 4 K. The no‐phonon line at v̄ = 5558 cm−1 is demonstrated to coincide with the inverse absorption transition. The luminescence shows medium coupling to ZnSe lattice vibrations. An exponential decay with a time constant τ = 100 μs is recorded. A rich fine‐structure is displayed by the 4T1(P) ← 4A2(F) absorption studied for comparison. Qualitatively, it can be described by spin–orbit and Jahn‐Teller interaction. Finally, the properties of two additional emission bands present in the 4200 to 5600 cm−1 region are illustrated, one of them dominated by a no‐phonon line at 5471 cm−1. Capture of a hole by a neutral donor is discussed as a possible interpretation of a broad luminescence band peaking near 4600 cm−1.
