Growth, mechanism and properties of TiO2 nanorods embedded nanopillar: Evidence of lattice orientation effect

Worldwide researchers and scientists are taking efforts to develop novel structured highly crystallized nanomaterials to fabricate devices for various applications. In this report, we demonstrate the synthesis of self-originated single phase Titanium dioxide (TiO2) nano rods embedded nanopillar on nanotent grain under simple hydrothermal method. Synthesized TiO2 nanopillars are in single crystalline tetragonal crystal structure with rutile phase. Understanding the fundamental crystal nucleation and growth mechanism is more critical in the semiconducting oxide thin films with controlled size and morphological features. The growth mechanism of TiO2 nanopillars on the surface of Fluorine doped Tin Oxide (FTO) substrate is explained in support of FESEM and AFM images. The optical emission properties are studied with photoluminescence spectroscopy. (C) 2017 Elsevier Ltd. All rights reserved.
