Abstract
We elucidate a facile method for the preparation of perovskite manganite nanotubes using a sacrificial template assisted pulsed laser deposition technique.
Highlights
The design, fabrication and modi cation of low dimensional materials can provide new materials for practical applications, and be fundamental to understanding the basic relationship among structure, defects, valence and spin in low dimensional solid science.[1]

We reported the utilization of Pulsed laser deposition (PLD) for high quality epitaxy lms of perovskite structure manganites and ferrites on SrTiO3 substrate.[36,37]
Summary
The design, fabrication and modi cation of low dimensional materials can provide new materials for practical applications, and be fundamental to understanding the basic relationship among structure, defects, valence and spin in low dimensional solid science.[1]. The general procedure of this method is (i) preparing relevant polymeric precursors, and (ii) lling the precursors into the porous templates, (iii) heat treating for the crystallization of perovskites, (iv) nally etching the template to obtain nanotubes Those chemical solution processes show signi cant advantages in size control and large amount synthesis, complicated operation steps and extremely toxic and unstable organometallic precursors are inevitable.[29] Pulsed laser deposition (PLD) is a versatile physical vapor deposition technique for fabricating multicomponent oxide lms with controllable stoichiometry.30 2-Dimensional mesh-like thin lms and high-density nanodot arrays have been directly prepared by PLD utilizing anodic aluminium oxide (AAO) as masks.[31,32,33,34] Template-assisted PLD has been only reported in PbZrO3 nanotube preparation,[35] the high quality nanotube fabrication process and growing kinetics still need further investigation. This method illustrated here can be possibly applied for most of inorganic tubular nanostructure preparations
