Talk:Zinc selenide

Maybe some mention of the fact that it falls under the class of compunds called chalcogenide should be included here.

Use in optical isolators
ZnSe has a reasonably large Verdet constant (roughly 1 min. cm-1G-1 at $$\lambda = 500$$nm) and was suggested for use in optical isolators, see Wunderlich J. A. and DeShazer L. G., Applied Optics 16 (6), 1584 (1977). Note that although the rare-earth orthoferrites have much higher Verdet constants, they are birefringent and aren't much good at producing large angles of rotation. However, I have found an article (Turner A. E. et al., Applied Optics 22 (20), 3152 (1983)) where dilute magnetic semiconductors, specifically Cd1-xMnxTe, are shown to have much higher Verdet constants and therefore lead to a more compact design. Unfortunately, I have no contact with any optical laboratories, so I don't know whether Zinc Selenide is still used for such purposes. Does anyone know? Woodford (talk) 07:20, 2 April 2008 (UTC)

ZnSe bandgap is well below blue light region
The claim that it can emit blue light seems very unlikely. Isn't this confused with zinc sulfide? Any link? FDominec (talk) 09:18, 26 October 2022 (UTC)


 * A band gap of 2.70 eV is equivalent to a wavelength of 459 nm, which is blue light.
