| Research Abstract |
Purpose and results of this project are shown as follows.
It will be carried out that thin film electroluminescent devices using an oxide-phosphor, Zn_2SiO_4 : Ti or ZnGa_2O_4, emitting layr prepared on a BaTiO_3 ceramic insulating layr as well as substrate emitts a high luminance of blue light from the low -driving voltage.
1) It is possible that various dopants can be introduced into the same host materials of Zn_2SiO_4 or ZnGa_2O_4.
2) These hosts are promising materials as the blue, green or red emitting layr of EL devices.
3) As-deposited Zn_2SiO_4 : Ti emitting layr prepared by magnetron sputtering do not emitts because the layr may include non-radiative centers. Consequently, the layr was needed post-annealing at high temperature.
4) It is difficult to prepare Zn_2SiO_4 host with a excellent crystallinity by chemical vapor deposition because SiO_2 always become amorphous in the ZnO-SiO_2. But CVD grown, for example, Zn_2SiO_4 : Mn emitts green light even EL devices with as-deposited emitting layr.
5) Thin film elecgtroluminescent devices using the ZnGa_2O_4 : Cr emitting layr showed the luminance as high as 195 cd/m2. These devices are promissing materials for red emitting one.
