Abstract
티타늄 금속판을 수증기 산화하여 만든 TiO2-x 박막과 TiO2 단결정을 알곤기체속에서 환원한 시료를 사용하여 이들의 광전기화학적 성질을 연구하였다. 1M NaOH전해질 용액에서 TiO2-x 전극에 200~800nm 사이의 광을 조사하였을 때 자외부 영역에서는 320nm에서, 가시부 영역에서는 520nm, 620nm 그리고 740nm에서 전류의 peak가 나타났다. 이미 보고된 것과는 대조적으로 가시부 영역의 이들 peak는 grating monochromator의 2차선의 영향에 의하여 나타난 것임이 밝혀졌다.

The thin films of TiO2-x, were prepared by vapor oxidation and TiO2 single crystal was reduced by heating in argon atmosphere. The photo-electrochemical properties of these samples were studied. When the photocurrent was scanned in 1M NaOH electrolyte solution, several peaks were observed in the vicinity of 320nm in the UV-region and in the vicinity of 520nm, 620nm, and 740nm in the visible-region. Contrary to the previous suppositions, those peaks were produced by the second-order lines from the grating monochromator.
