  • The present status and prospects for further development of thin-film electroluminescent (TFEL) devices using oxide phosphors are described. High-luminance oxide TFEL devices have been recently developed using a new combinatorial deposition technique featuring rf magnetron sputtering with a subdivided powder target. In addition, new flexible oxide TFEL devices have been fabricated on an oxide ceramic sheet and operated stably in air above $200^{\circ}C$.

  • Diamond film was deposited on Mo substrate at atmospheric pressure using combustion flame apparatus with the addition of H2. At a temperature above 100$0^{\circ}C$, parts of the film were converted into graphites and these were etched by hydrogen atoms. With increasing $C_2H_2/O_2$ ratio, the nucleation density of the film increased. But the greater part of the film was formed with cauliflower-shaped amorphous carbon. These amorphous carbn were crystallized etching amorphous carbon.

  • 광섬유 모재제조공정인 OVD와 VAD방식에서의 입자부착 증진을 위해서 외부에서 전기장을 가 해서 실리카입자를 대전시킨 뒤에 타겟으로 부착을 시키는 전기영동원리를 이용하는 방법을 소 개하였다. 실험에서는 디스크형 타겟을 사용하여 타겟 근방에서의 온도, 전기장분포를 측정하였고 입자부착실험을 수행했다. 그 결과 9cm 타겟에 -1.6kv가 가해\ulcorner을 때 전기영동으로 인한 부착률 증가는 열영동으로 인한 효과의 약 35%가 되었다.
