More Information
Summary:Disclosed are photoluminescent long afterglow phosphors comprised of alkaline earth aluminates activated by rare earths and enhanced by phosphors are expressed by the formula: M1-x(Al1-yBy)2O4-x-z:RE, wherein M is at least one alkaline earth metal selected from alkaline earth group consisting of Ca, Sr, Ba and Mg, and wherein -1</=x</=0.90, 0</=y</=0.5, 0<z<2, and wherein RE represents europium and at least one additional lanthanide which serve as activator and co-activator(s). L'invention concerne des phosphores à longue rémanence photoluminescents qui comprennent des aluminates alcalino-terreux activés par des éléments des terres rares et améliorés par des phosphores de formule M1-x(A11-yBy)2O4-x-z:RE dans laquelle M représente au moins un métal alcalino-terreux sélectionné dans le groupe alcalino-terreux constitué de Ca, Sr, Ba et Mg et où -1</=x</=0,90, 0</=y</=0,5, 0<z<2, et dans laquelle RE représente un europium et au moins un lanthanide servant d'activateur et de co-activateur(s).
