摘要:We report the successful synthesis of ZnO porous nano-cages with controllable hollow spaces by simply using laser ablation of Zn target in liquid medium containing deionized water and ammonia (V-water:V-ammonia = 7:1 similar to 5:1). In addition to the porous surface, the created interior space of the ZnO nano-cage substantially increases with the ammonia concentration. The related growth mechanism has been illustrated based on the ultra-rapid alkaline etching process. Moreover, numerous Zn(NH3)(4)(2+) clusters generated by the selective etching route readily penetrate into the ZnO porous structures and can be embedded in these unique nano-cages. It is envisaged that these composite ions/ZnO porous nano-cages have significant implications for gas sensing and catalytic applications. The synthetic scheme used here should also be applicable to other semiconductors. (C) 2014 Optical Society of America
