Abstract
Introduction of Cu into does not interfere with the red Eu++ emission. Excitation of the blue emission is more effective by 3650Aå than by 2537Aå. Firing with excess Cu gives rise to deposits of free which may cause an efficient system of contact electroluminescence. The electroluminescent properties depend on the physical characteristics of the phosphors, including its state of agglomeration. At moderate concentrations of Eu, the blue emission of is entirely suppressed in electroluminescent excitation.Keywords
