Abstract

NUEVAS SUSTANCIAS FOSFORESCENTES DE OXIDOS, BASADAS EN OXIDOS DE GALIO DOPADOS, GALATOS Y GERMANATOS ALCALINOTERREOS, PARA MATERIALES DE DISPOSITIVOS DE VISUALIZACION ELECTROLUMINISCENTES. SE HA OBTENIDO POR PRIMERA VEZ UNA ELECTROLUMINISCENCIA ROJA NARANJA BRILLANTE EN OXIDOS AMORFOS Y CRISTALINOS GA SUB,2}O SUB,3}:EU. SE HAN PREPARADO SRGA SUB,2}O SUB,4} Y SRGA SUB,4}O SUB,9} DOPADO CON 1-8 MOL % DE EU Y TB, CAGA SUB,2}O SUB,4}, CA SUB,3}GA SUB,2}O SUB,6} Y CAGA SUB,4}O SUB,7} DOPADOS CON 1-4 MOL % DE EU, TB, PR Y DY, BAGA SUB,2}O SUB,4} DOPADO CON 1-2 MOL % DE EU Y TB, UTILIZANDO PULVERIZACION IONICA DE MAGNETRON RF SOBRE SUSTRATOS DIELECTRICOS CERAMICOS Y RECOCIDOS A 600-950 (GRADOS) C EN AIRE O AR, DURANTE 1-2 HORAS. SE OBTUVO UNA EMISION DE ELECTROLUMINISCENCIA (EL) BRILLANTE, CON LONGITUDES DE ONDA QUE CUBRIAN EL ESPECTRO VISIBLE ENTRE 400 Y 700 NM, Y EMISION INFRARROJA POR ENCIMA DE 700 NM, CON PICOS ESPECTRALES CARACTERISTICOS DE LAS TRANSICIONES DE LAS TIERRAS RARAS. LAS PELICULASDE CAGA SUB,2}O SUB,4} CON 1 MOL % DE EU, LOGRARON 22 FL (75 CD/M SUP,2}) A 60 HZ Y PRESENTARON UNA EFICIENCIA MAXIMA DE 0,2 LM/W PARA LA EMISION ROJA. UNA PELICULA FINA AMORFA DE CA SUB,3}GA SUB,2}O SUB,6} CON 2 MOL % DE EU, LOGRO 34 FL EN EL ROJA A 60 HZ, CUANDO SE RECOCIO A 600 (GRADOS) C. SRGA SUB,2}O SUB,4} CON 1 MOL % DE EU Y 4 MOL % DE TB, PRODUJO UNA SUSTANCIA LUMINISCENTE "BLANCA" CON EMISION ROJA, VERDE Y AZUL (13 FL A 60 HZ), Y SRGA SUB,2}O SUB,4} CON 8 MOL % TB, PRODUJO UNA SUSTANCIA LUMINISCENTE AZUL Y VERDE, CON UNA MEDICION DE 30 FL A 60 HZ. ZN SUB,2}SI SUB,0,5}GE SUB,0,5}O SUB,4} QUE CONTENIA MN SE PULVERIZO IONICAMENTE UTILIZANDO PULVERIZACION DE RADIOFRECUENCIA DE MAGNETRON, SOBRE SUSTRATOS DIELECTRICOS Y RECOCIDOS A 700 (GRADOS) C, DURANTE 1 HORA, EN AIRE O ARGON. SE OBTUVO UNA UNA EMISION VERDE BRILLANTE (540 NM): 110 FL (377 CD/M SUP,2}) A 60 HZ, CON UNA EFICIENCIA MAXIMA DE 0,9 L/W. SE OBTUVO ASIMISMO UNA EMISION ROJA, MODERADAMENTE BRILLANTE (640 NM).
