The novel phosphor is based on doped alkaline earth gallate for electroluminescent (EL) displays. Bright red EL was obtained in crystalline and amorphous alkaline earth gallate doped with europium. Sr 4 Ga 2 O 7 , Sr 7 Ga 4 O 13 , Sr 3 Ga 2 O 6 , Sr 3 Ga 4 O 9 , SrGa 4 O 7 , SrGa 12 O 19 , Ba 4 doped with 1-2% Eu Powder targets with compositions of Ga 2 O 7 , Ba 3 Ga 2 O 6 and Ca 3 Ga 4 O 9 % Eu were doped with 1-2% Eu and RF magnetron sputtered onto the BaTiO 3 substrate. Both the annealed and deposited films had bright peaks in the red part of the visible spectrum with peaks characteristic of Eu 3+ ions. |
