Abstract
PROCEDIMIENTO CONTINUO DE PREPARACION DE POLVOS FLUORESCENTES CONSTITUIDOS POR UNA MATRIZ OXIDICA DOPADA CON COLORANTES ORGANICOS. SE DESCRIBE UN PROCEDIMIENTO CONTINUO DE PREPARACION DE POLVOS FLUORESCENTES CONSTITUIDOS POR PARTICULAS ESFERICAS (0.2 Y 6) DE UNA MATRIZ OXIDICA DOPADA CON UN COLORANTE ORGANICO. EL METODO SE BASA EN LA HIDROLISIS DE AEROSOLES LIQUIDOS CUYA COMPOSICION ES UNA MEZCLA DE UN PRECURSOR METALICO LIQUIDO E HIDROLIZABLE Y UNA DISOLUCION ORGANICA DEL COLORANTE FLUORESCENTE. COMO MATRIZ PUEDE SELECCIONARSE CUALQUIER OXIDO METALICO QUE PRESENTE COMPUESTOS LIQUIDOS HIDROLIZABLES U OXIDOS MIXTOS OBTENIDOS POR MEZCLAS DE LOS ANTERIORES. LOS MATERIALES OBTENIDOS PRESENTAN UNA MEJORA SENSIBLE DE LAS PROPIEDADES OPTICAS CON RESPECTO A LAS DE LOS COLORANTES EN DISOLUCION, AUMENTANDO LA PUREZA OPTICA Y EL RENDIMIENTO CUANTICO. ASIMISMO DICHOS MATERIALES PRESENTAN ESTABILIDAD OPTICA Y RESISTENCIA AL ATAQUE QUIMICO CON SOLVENTES. UNA APLICACION IMPORTANTE SE REFIERE A LA PREPARACION DE MATERIALES CERAMICOS CON PROPIEDADES OPTICAS.
