We provide measurements to support our earlier report of continuous wave fiber lasing in a small core Ce 3+-doped selenide chalcogenide SIF (step index fiber) of core: Ge-As-Ga-Se chalcogenide glass, doped with 500 ppmw (parts-per-million by weight) of cerium(III). In-band pumping of Ce 3+ in fiber, bulk glass and ground glass geometries, at 4.15 µm wavelength, gives MIR (mid-infrared) photoluminescence spanning 3.40-5.80 μm wavelength, corresponding to the 2 F5/2  2 F7/2 electronic emission transition due to Ce 3+. Room temperature emission and MIR absorption spectra together enable interpretation of the manifold energies of the first excited state and there is potential for occupied Stark levels in the ground state at room temperature. Both 'í µí¼rad' (PL lifetime) and 'trise' (rise-time through 10% to 90 % of maximum PL intensity) are determined: for ground glass at 4.60 µm wavelength, the best decay fit comprises a primary, and perhaps secondary, lifetime for ground glass of 3.5 ms, and 1.2 ms, and PL rise time of 3.9 ms.
