| titleOfInvention | Doped amorphous and crystalline gallium oxide, alkaline earth metal gallate and doped zinc germanate phosphors used as electroluminescent materials |
| abstract | The present invention provides novel oxide phosphors based on doped gallium oxide, alkaline earth metal gallate and germanate for use in electroluminescent display materials. Bright orange red electroluminescence was obtained for the first time in amorphous and crystalline oxide Ga 2 O 3 : Eu. SrGa 4 O 9 doped with 1-8 mol% Eu and Tb, CaGa 2 O 4 , Ca 3 Ga 2 O 6 and CaGa 4 O doped with 1-4 mol% Eu, Tb, Pr and Dy BaGa 2 O 4 doped with 7 , 1-2 mol% of Eu and Tb was RF magnetized sputtered on a ceramic dielectric substrate and annealed in air or Ar for 1 to 2 hours at 600 ° C to 950 ° C. As a result, it was possible to observe a bright electroluminescence (EL) emission phenomenon with a wavelength corresponding to more than 700nm infrared radiation having a characteristic spectral peak of the rare earth transition and a visible spectrum of 400 to 700nm.n n n A film of CaGa 2 O 4 doped with 1 mol% Eu achieved 22 fL (75 cd / m 2 ) at 60 Hz, with a maximum efficiency of 0.2 lm / w for red emission. An amorphous thin film of Ca 3 Ga 2 O 6 doped with 2 mol% of Eu achieved 34 fL of red EL at 60 Hz when annealed at 600 ° C. SrGa 2 O 4 doped with 1 mol% Eu and 4 mol% Tb provided a "white" phosphor with red, green and blue emission (13 fL at 60 Hz) and doped with 8 mol% Tb. SrGa 2 O 4 provided blue and green phosphors (30 fL at 60 Hz). Zn 2 Si 0.5 Ge 0.5 O 4 containing Mn was sputtered onto the ceramic dielectric substrate by magnetron RF sputtering and annealed in air or argon at 700 ° C. for 1 hour. As a result, bright green electroluminescence (540 nm) radiation was obtained (110 fL (377 cd / m 2 ) at 60 Hz, maximum efficiency 0.9 l / w). A moderately bright red emission (640 nm) was also obtained. |
