Abstract

Nanocomposite of Te doped $SiO_2$ films was prepared for the new functional materials like non-linear optic materials, selective absorption and transmission films. The effects of particle size and morphology with different hydrolysis conditions on the properties were examined with TGA/DTA. XRD. UV-spectrometer, SPM, SEM and EDS. It was found that Te/$SiO_2$ films showed high absorption peak at 550nm visible region by plasma resonance of Te fine particles. The Rm surface roughness of the films was about 2.5 nm and the size of Te particles was 5~10nm.

Te(Tellurium) 미립자를 $SiO_2$ 박막에 분산시켜 비선형 광학재료, 선택흡수막 및 투과막 등 새로운 기능성 재료로 활용하기 위하여 Te/$SiO_2$ 나노 목합체 박막을 제조하였다. 가수분해 조건을 변화시켰을 때 박막표면에 분산시킨 입자의 크기와 형상이 재료의 물성에 미치는 영향을 열처리 후의 시차중량분석과 엑스선 회절분석, 분광분석, 원자력간 현미경 그리고 전자현미경 관찰 등을 통하여 조사하였다. 제조된 박막의 광흡수 스펙트럼에스 Te 미립자의 플라즈마 공명에 의한 550nm 부근의 흡수피크가 관찰되어 비선형 광학성을 확인할 수 있었다. 박막의 표면 거칠기는 약 2.5nm 내외였고, Te 미립자의 크기는 약 5~10nm였다.
