摘要：
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. © 2016, Science Press.
