Different molar concentrations (0.05-0.2 M) of vanadium pentoxide nanoparticles were synthesized with and without polyvinylpyrrolidone (PVP) using hydrothermal method. The growth mechanism with different molar concentrations as well as the effect of PVP on the structural, optical, and electrical properties have been investigated. The size of the particles was measured from transmission electron microscopy (TEM) and x-ray diffraction spectroscopy (XRD). Optical properties were analyzed through photoluminescence and absorption measurement. The electrical transport properties were analyzed by impedance spectroscopy and Van der Pauw method. From impedance measurements, dominance of grain boundary resistance over grain resistance was observed. The resistivity also decreased with increasing molar concentrations of nanoparticles with and without PVP. The highest temperature coefficient of resistance (TCR) value of À 2.33 %/K with the lowest resistivity of 0.02 Ω. cm for V 2 O 5 nanoparticle of 0.2 M concentration without using PVP was observed. Therefore, such V 2 O 5 nanoparticles are a potential material for microbolometer applications.

gained a constantly growing interest in this field, due to their ability to tune the material properties according to the oxidation state. Among them, vanadium pentoxide (V 2 O 5 ) exhibits both anodic and cathodic coloration, and thus the reversible lithium ion insertion/ extraction processes lead to not only reversible changes in optical parameters but also multicolor changes for esthetics in the voltage range of AE1 V. [1][2][3] Also, it was suggested that a structure with well-aligned atomic planes along z-direction is very favorable for intercalation of hosts for Li ions, such as in rechargeable batteries and electrochromic devices. [2,4,5] In addition, such a wellaligned structure would also enhance the Liþ diffusion through the solvent.An efficient way to enhance the intercalation process of Li atoms in batteries or electrochromic devices is the fabrication of nanostructured layers with well-aligned atomic planes along z-axis. Different methods were proposed to obtain nanostructured V 2 O 5 , such as electrospinning of V 2 O 5 nanofibers, electrostatic spray deposition, deposition of V 2 O 5 nanowires from chemical vapor transport, dip coating, and spray pyrolysis technique. [6][7][8] Regarding spray pyrolysis technique, this has been proved to be
