Process for fabricating electroluminescent device |
摘要 |
A process for fabricating a blue-emitting SrS:Ce based electroluminescent device, which improves in brightness and blue color purity of the electroluminescent device, is disclosed. The blue-emitting luminescent layer of the device is formed as follows: a luminescent layer based on strontium sulfide (SrS) with cerium (Ce) doped at a concentration in a range of 0.01% by atomic or higher but less than 0.3% by atomic is deposited; and then heat treatment is applied thereto at a temperature in a range of 400 DEG C. or higher but 550 DEG C. or lower before forming any other layer thereon.
