摘要

NEW SUBSTANCES phosphorescent OXIDE, GALLIUM OXIDES BASED doped gallates and germanates alkaline MATERIALS ELECTROLUMINESCENT DISPLAY DEVICES. HAS BEEN OBTAINED FOR THE FIRST TIME electroluminescence BRIGHT RED ORANGE amorphous and crystalline oxides GA SUB, 2} O SUB, 3}: EU. Were prepared SRGA SUB, SUB O 2}, 4} SRGA SUB, SUB 4 O} 9} doped 01.08% MOL US and TB, CAGA SUB, SUB 2 O} 4}, CA SUB, 3} GA SUB, SUB 2} O 6} Y CAGA SUB, 4} O SUB, 7} doped EU 1-4 mol-%, TB, PR and DY, Bàga SUB, SUB 2 O} 4} DOPING with 1-2 MOL% US and TB, SPRAYING USING RF magnetron IONIC DIELECTRIC cERAMIC substrates and annealed at 600-950 (degrees) C in air or AR, for 1-2 hours. OBTAINED A electroluminescence emission (EL) Brillante, WAVELENGTH SPECTRUM VISIBLE covering between 400 and 700 nm, INFRARED EMISSION above 700 nm, SPECTRAL PEAKS TRANSITIONS characteristic of rare earths. THE PELICULASDE CAGA SUB, SUB 2 O} 4} with 1 mol% of EU, FL ACHIEVED 22 (CD 75 / M SUP, 2}) 60 HZ AND PRESENTED A MAXIMUM EFFICIENCY 0.2 LM / W for issuance RED. A thin film amorphous CA SUB, SUB GA 3} 2} O SUB, 6} with 2 mol-% US, 34 FL ACHIEVEMENT IN RED 60 HZ, WHEN annealed at 600 (DEGREES) C. SRGA SUB, 2} O SUB, 4} with 1 mol% US and 4 mol% Tb, produced a LUMINESCENT "WHITE" substance red emission, green and blue (13 FL 60 HZ), Y SRGA SUB, 2} O SUB , 4} with 8 mol% TB, it produced a phosphor blue and green, with a measurement of 30 FL 60 HZ. ZN SUB, 2} IF SUB, SUB GE} 0.5, 0.5} O SUB, 4} containing MN sprayed ionically USING RADIO FREQUENCY MAGNETRON SPRAYING, DIELECTRIC SUBSTRATES ON and annealed 700 (DEGREES) C DURING 1 hour in air or argon. It OBTAINED A EMISSION A BRILLIANT GREEN (540 NM): 110 FL (377 CD / M SUP, 2}) 60 HZ, maximum efficiency of 0.9 L / W. It was also obtained a, moderately bright (640 nm) red emission.
