The spectroscopic characterization and Vitality transfer system of iron-chromium co-doped ZnSe polycrystalline (Cr,Fe:ZnSe) ended up noted with dimension of 15 mm × 15 mm × two mm obtained by controlled submit-progress thermal diffusion system. The infrared absorption is characterised by a strong wide-band centered at 1770 nm which may be attribu… Read More
