摘要

介绍了纳米多孔氧化铝高温退火制备多晶阳极氧化铝的工艺。研究了红外光谱范围内的光学特性。研究表明，基于多晶氧化铝的纳米孔陶瓷比氧化铝陶瓷刚玉具有更宽的带宽和更高的透明度。对AAO各相的红外光谱分析表明，随着退火温度的升高，透明窗口变宽，并向长波部分转移:从非晶AAO的$5.5\ \boldsymbol{\mu} \mathbf{m}$到多晶AAO的$5 \mu \mathbf{m}$。

Optical Properties of Nanoporous Polycrystalline Anodic Alumina in the IR Region

The technology of polycrystalline anodic aluminum oxide (AAO) formation by high-temperature annealing of nanoporous alumina is described. Optical properties in the infrared (IR) spectral range are investigated. It has been revealed that nanoporous ceramics based on polycrystalline AAO has a wider bandwidth and higher transparency than aluminum oxide ceramic corundum (poycor). Analysis of various phases of AAO in the IR range showed that the transparency window widens with the increasing annealing temperature and shifts to the long-wave part of the spectrum: from $5.5\ \boldsymbol{\mu} \mathbf{m}$ for amorphous AAO to $5 \mu \mathrm{m}$ for polycrystalline AAO.
