The Photoluminescence spectra and lifetime of Fe2+ doped ZnSe crystal with quantum cascade laser pumping is measured. At room temperature the photoluminescence lifetime is ∼ 0.38 μs, which increases to ∼ 100 μs at 80K.
Room temperature photoluminescence in Fe:ZnSe is observed under near-absorption-edge Quantum Cascade Laser (QCL) pumping. Both the spectral characteristics (λpeak ≈ 4.7 μm) and the luminescence lifetime (τ ≈ 0.38 us) are measured.
