We observe an anomalous 's-shaped' temperature dependence of emission energy and a severe decrease of emission intensity with the increase of temperature. ... We report photoluminescence (PL) study of Be x Cd 1Kx Se epitaxial layers (x!0.21) grown by molecular beam epitaxy on InP substrates. ... Although Be x Cd 1Kx Se is used as an active layer in optically pumped lasers  and current injected LEDs  , there is a limited knowledge of its luminescent properties. ...doi:10.1016/j.mejo.2005.06.005 fatcat:wiop36evufdolpo3ab45lctsha
