中文摘要	介绍了一种采用宽禁带半导体二氧化钛纳米管阵列薄膜材料制备beta伏特效应同位素电池的方法.通过对金属钛片的电化学阳极氧化制备了垂直定向、有序排列的二氧化钛纳米管阵列薄膜,研究了退火条件对二氧化钛纳米管阵列薄膜半导体光电性能的影响.通过与镍-63辐射源的集成封装,形成三明治结构镍-63/二氧化钛纳米管阵列薄膜/钛片的beta伏特同位素电池.实验结果表明,基于氩气氛围下450℃退火的黑色二氧化钛纳米管阵列薄膜具有高的氧空位缺陷浓度和宽的可见-紫外吸收光谱.在使用beta辐射总能量为10 mCi的镍-63辐射源时,同位素电池的开路电压为1.02 V,短路电流75.52 nA,最大有效转换效率为22.48%.
英文摘要	This work is to develop a high-reliability long-life high-conversion-efficiency radio-isotope microbattery in order to meet power requirements of micro-electromechanical systems,micro-sensors,micro-actuators,wireless sensing net,and other electron devices working in harsh circumstances,such as polar,desert,subsea,outer surface,etc.Compared with traditional dry batteries,chemical batteries,fuel cells and solar cells,the radioactive isotope batteries have long service life,higher energy density,strong adaptability to environment,good work stability,no maintenance,and miniaturized size,etc.These advantages make the beta voltaic battery an attractive alternative.In this paper we present a beta voltaic battery with enhanced beta voltaic effect by using a wide-bandgap semiconductor TiO_2 nanotube array thin film.An electrochemical anodic oxidation method is used to prepare the vertically oriented and highly ordered TiO_2 nanotube array film on Ti plate.Electrolyte solution consists of ammonium fluoride,ethylene glycol,and deionized water.The structure(TiO_2 nanotube array with diameter about 80-100 nm,wall thickness about 15-25 nm,and length 9 mum) is characterized by field emission scanning electron microscope.The microstructure of the TiO_2 nanotube array is characterized using X-ray diffraction.The effects of annealing condition on optical and electrical properties are studied.The electrical property is characterized by Keithley model 2450 source meter semiconductor characterization system in dark at room temperature.The beta voltaic batteries are assembled as a sandwiched structure(~(63)Ni/TiO_2 nanotube arrays film/Ti) using a radioisotope~(63)Ni plate and TiO_2 nanotube array films.The experimental results show that the black TiO_2 nanotube array film annealed at 450 ℃ in argon atmosphere could creates high visible-ultraviolet absorption due to a great many of oxygen vacancy defects generated in TiO_2 nanotube array film.The oxygen vacancy signals are found by electron spin resonance.Compared with the planar structure,the nano-porous array structure has strong absorption to beta particles:most of the beta particles enter into the pores and are reflected or absorbed by the surface of the tube walls.With a 10 mCi~(63)Ni radiation source,the beta voltaic battery using black TiO_2 nanotube array film can generate an open-circuited voltage of 1.02 V,a short-circuited current of 75.52 nA,and a maximum effective conversion efficiency of 22.48%.
