초록
본 연구에서는 바나듐 산화물(VO2)과 텅스텐이 도핑된 바나듐 산화물(W-VO2) 분말을 바나듐 산화물(V2O5)과 옥살산수화물로부터 수열합성과 하소공정을 통하여 성공적으로 제조하였다. 시료들의 결정구조와 열변색 특성들은 FE-SEM, XRD, XPS, DSC 및 UV-Vis-NIR 분광기를 이용하여 분석하였다. W-VO2 시료에 W의 도핑량을 증가시키면, W-VO2 시료의 상전이 온도가 70 ℃에서 42 ℃로 낮아지는 경향이 있었다. 또한, W-VO2 시료를 상전이 온도 이상으로 가열시키면 UV-Vis-NIR 곡선이 가시광 영역에서는 변하지 않고 NIR 영역에서는 낮은 투과도 방향으로 이동하는 경향이 있었다.
Vanadium oxide (VO2) and tungsten-doped vanadium oxide (W-VO2) powder, well known as thermochromic materials, were prepared from vanadium pentoxide (V2O5) and oxalic acid dihydrate by hydrothermal and calcination process. The crystal structure and thermochromic property of samples were analyzed using FE-SEM, XRD, XPS, DSC, and UV-Vis-NIR spectroscopy. With increasing the doping amount of W, the phase transition temperature of W-VO2 sample decreased from 70 ℃ to 42 ℃. When heating W-VO2 sample above the phase transition temperature, the UV-Vis-NIR spectrum was not changed in the visible range and shifted towards a low transparency in the full name (NIR) region.
