摘要

以乙醇-草酸混合溶液为电解液

用二次阳极氧化法制备纳米多孔Al

:C薄膜。在制备过程中

碳的掺杂浓度可控。实验结果表明

随着碳浓度的增加

热释光强度逐渐增大;随着退火温度的升高

320 ℃左右的主热释光峰的强度先升高后降低。在退火温度为500 ℃时

主热释光峰的强度达到最大。纯草酸溶液制备的Al

薄膜的热释光剂量响应曲线在10~50 Gy是线性的

在50~100 Gy呈超线性;而乙醇-草酸混合溶液制备的Al

:C薄膜在10~100 Gy基本呈线性。

Abstract

The carbon-doped nanoporous alumina films were prepared by two-step anodic oxidation in ethanol-oxalic acid mixture. This kind of doping method can effectively control the doping concentration of carbon. The thermoluminescence (TL) measurements show that the TL intensity of the films prepared in ethanol-oxalic acid mixture has been significantly improved comparing with the film prepared in oxalic acid

and the TL intensity increases with the carbon concentration. The TL intensity at 320 ℃ first increases then decreases with the elevated annealing temperature and reaches a maximum value at 500 ℃. The films prepared in oxalic acid show a linear dose response in the dose range of 10-50 Gy and a superlinear dose response in the range of 50-100 Gy

while the films prepared in ethanol-oxalic acid mixture show a linear dose response in the range of 10-100 Gy.
