Abstract

We report the synthesis and characterization of quartz nanocrystals (NCs). Quartz NCs were synthesized from the dissolution of amorphous silica nanoparticle precursors under the mild hydrothermal condition of ~250 ℃ and autogenic pressure. It was confirmed that the average size of the nanostructure with a highly crystalline phase of α-quartz can be tuned in a relatively narrow range from 407.5 to 826.2 nm with respect to the reaction time. α-Quartz NCs have potential uses for technological applications in optoelectronics, sensing, and rechargeable battery devices.

본 연구에서는 석영 나노 결정의 합성과 특성 분석을 진행하였다. 비정질 실리카 나노 입자 전구체가 용해된 용액을 섭씨 250도 온도와 자가 압력의 온건한 열수 반응 하에서 석영 나노 결정을 성공적으로 합성하였다. 합성된 나노 결정의 화학적 조성과 구조 분석을 시행하였다. 알파 석영의 특징적인 고결정질 상의 나노 구조를 가지는 석영 나노 결정의 평균 크기는 반응 시간에 따라 407.5 에서 826.2 nm까지 비교적 좁은 범위에서 조정될 수 있음을 발견하였다. 본 연구를 통해 발견된 석영 나노 입자는 광전자, 센서, 및 충전식 배터리 소자의 기술 응용에 매우 중요한 잠재적 용도가 있을 것으로 사료된다.
