Light-weight sodium alanate thin films grown by reactive sputtering
摘要：
本文报道了在氢原子反应气氛中用共溅射法制备铝酸钠薄膜的方法。我们研究了相的形成和分布，以及氢的脱附，与光学和红外透射光谱相结合。我们表明，氢的脱附，相分离和掺杂剂在这些复杂的金属氧化物中的作用，可以监测与光学测量。这一结果表明，薄膜方法可用于技术相关的轻金属陶瓷的模型研究。
英文摘要：
We report the preparation of sodium alanate, a promising hydrogen storage material, in a thin film form using co-sputtering in a reactive atmosphere of atomic hydrogen. We study the phase formation and distribution, and the hydrogen desorption, with a combination of optical and infrared transmission spectroscopy. We show that the hydrogen desorption, the phase segregation and the role of the dopants in these complex metal hydrides can be monitored with optical measurements. This result shows that a thin film approach can be used for a model study of technologically relevant lightweight metal hydrides.
