摘要

以水热法制备了由纳米棒组成的二氧化钛阵列。通过控制反应时间，对组成阵列的二氧化钛纳米棒的尺寸进行调节。利用扫描电镜和X射线衍射光谱分析了样品的形貌和晶体结构，发现将反应时间由4 h延长至8 h，二氧化钛纳米棒的直径由100 nm增大到200 nm。利用紫外-可见吸收光谱测量了样品的光吸收特性，发现了尺寸效应引起的吸收边和带隙变化，反应时间由4 h延长至8 h，样品带隙由3.09 eV变化至2.97 eV。利用荧光光谱研究样品的光致发光性能，发现了样品的近带边发光（382 nm左右）、自陷激子发光（420 nm左右）、束缚激子发光（456 nm左右）和缺陷能级发光（492 nm左右）。

Abstract

TiO

array was synthesized by hydrothermal method. The scanning electron microscopy(SEM) and X-ray diffraction(XRD) are used to detect their morphology and structure. The average diameter of TiO

nanorods was increased from 100 nm to 200 nm

when the hydrothermal reaction time changed from 4 h to 8 h. UV-vis spectra were used to detect their absorption properties. The TiO

array with shorter diameter shows blue shift of absorption edge and broadened band gap. The band gap of TiO

nanorod was decreased from 3.09 eV to 2.97 eV

when the hydrothermal reaction time changed from 4 h to 8 h. Photoluminescence spectra were used to detect their optical properties. Near absorption edgee mission(about 382 nm)

self-trapped exciton emission(about 420 nm)

bound exciton emission(about 456 nm)

and defect site emission(about 492 nm) are obtained under the examination by PL spectra.
