Abstract

UN PROCEDIMIENTO MEJORADO PARA FABRICAR UNA LAMPARA DE DESCARGA EN VAPOR DE MERCURIO A BAJA PRESION. LA LAMPARA COMPRENDE UNA ENVOLVENTE TRANSMISORA DE RADIACION, MEDIOS PARA MANTENER LA DESCARGA DURANTE EL FUNCIONAMIENTO Y UN RELLENO IONIZABLE QUE COMPRENDE UN GAS NOBLE Y MERCURIO. LA OBTENCION DE LA NOBLE PANTALLA SE EFECTUA APLICANDO UN MATERIAL LUMINISCENTE ACTIVADO POR PLOMO Y AL MENOS UNO DE LOS ELEMENTOS TERBIO Y MANGANESO SOBRE LA SUPERFICIE INTERIOR DE LA ENVOLVENTE, DONDE EL MATERIAL LUMINISCENTE TIENE LA ESTRUCTURA DE CRISTAL HEXAGONAL DEL APATITO Y UNA COMPOSICION TAL COMO ME<A(LN<B(AO<4)<6X<2; H REPRESENTA AL MENOS UNO DE LOS ELEMENTOS Y Y LA, EL CUAL PUEDE AL MENOS EN PARTE SER SUBSTITUIDO POR GADOLINIO.
