Abstract  : Recently,  anisotropic,  particularly,  one-dimensional  (1D)  ferroelectric 
perovskite nanostructures have been of high interest due to a number of unique 
properties.  Despite  the  existing  works  about  the  synthesis  of  such  1D 
nanostructures, there remain issues of fine-tuning the particle morphology due to 
the complex mechanism of particle formation. Therefore, in this paper, an attempt 
was made to describe the influence of the crystallization mechanism as well as 
hydrothermal synthesis parameters (such as reagent nature, pH, concentration, 
surfactant, heat treatment mode) on the peculiarities of the anisotropic growth and 
the formation of the 1D perovskite nanostructures. 

Keywords  : PEROVSKITE,  NANOSTRUCTURE,  ANISOTROPY,

I.  Introduction

The perovskite-type  compound  with  the  general formula of ABO3 (Fig.1)  is  the most 
studied ferroelectric oxides due to the unique dielectric and ferroelectric properties1,2. 
Compositions based on the BaTiO3, SrTiO3, PbTiO3 and PbZrO3 form solid solutions 
with each other and with a large number of other oxides and provide an enormous va -
riety of ferroelectric properties3. Particularly, BaTiO3 and Pb(Zr,Ti)O3 are widely used 
for its high dielectric and piezoelectric coefficients, respectively4,5. It makes this mate-
rial widely  used  in  non-volatile  digital  memories,  thin-film  capacitors,  electronic 
transducers, actuators, high-k dielectrics* as well as pyroelectric sensors, electrooptic 
modulators, optical memories and nonlinear optics6. 

Figure  1:  Perovskite structure.  i) A-site  (dodecahedral 
coordination) with (Ba,Ca,Na, K, Sr, Pb) cations; ii) B-site (octahedral 
coordination) with (Ti,Zr, Nb,Ta) cations; iii) BO6 oxygen octahedral 

Recently,  increasing  attention  is  paid  to  the  one-dimensional  (1D)  ferroelectric 
nanostructures  including  nanowires,  nanorods,  and  nanotubes  due  to  the  excellent 
performance  in  nanoelectronic,  photoelectronic,  and data  storage devices7,8,9,1011,12,13. 
Recently, the 1D perovskite nanostructures have attracted attention in such application 
as nano-sensors and catalysts for the integration in the current electronic devices10,14,15, 
biological materials (mimicking of the ion channels, drug delivery systems, stem cells 
investigation),  photodetectors,  solar  cells,  building  blocks  for  laser  applications, 
etc8,16,17.
