Abstract

PERFECCIONAMIENTOS INTRODUCIDOS EN UNA LAMPARA DE DESCARGA EN VAPOR DE MERCURIO A BAJA PRESION. CONSTA DE UNA PANTALLA LUMINISCENTE QUE COMPRENDE UN METABORATO DE METALES DE TIERRAS RARAS, DEFINIDO COMO (Y LA) <-<X<-<Y<-<Z CE<XGD<YTB<Z (MG, ZN) <-<P MN<PB O ; EL MAGNESIO Y/O EL ZINC PUEDEN SER SUSTITUIDOS TOTAL O PARCIALMENTE POR CADMIO. TANTO A CANTIDADES BAJAS COMO ALTAS DE CD, SE RETIENE LA ESTRUCTURA CRISTALINA MONOCLINICA DEL BORATO, Y SE OBTIENEN MATERIALES LUMINISCENTES CUYA EFICACIA CUANTICA, PUEDE SER TAN ALTA COMO LA DE LOS MATERIALES QUE CONTIENEN SOLO MG Y/O ZN.
