Biological and Optical Applications of Y2Ti2O7 Nanoparticle Using Microwave – Assisted Method

Abstract

The Pyrochlore type Yttrium Titanate (Y₂Ti₂O₇) nanoparticle (YTO) was successfully synthesized by microwave assisted method with the suitable temperature conditions. To analyze, several properties of physical, chemical, optical and biological nature, the synthesized Y₂Ti₂O₇ (YTO) nanoparticle was employed to such studies including XRD, SEM, EDAX, FTIR, UV-vis-NIR, PL, TG/DTA and anti-microbial activities. The XRD results confirmed the lack of secondary phases associated with the Y - Ti - O complex structure. In the morphological result shows the uniform semi-cylindrical domains were eventually identified and distributed with the presence of Yttrium and Titanium oxides which suggesting the formation of Y₂Ti₂O₇  (YTO) nanoparticles using SEM and EDAX analysis. Also, FTIR shows the Y – O stretching vibration and Ti⁴⁺ complex, in the synthesized Y₂Ti₂O₇ (YTO) nanoparticle. For its potential optical applications, the optical studies were carried out from PL spectrum and UV-vis-NIR with Tauc plot analyses of straight energy transition in the range of band gap (3.2 eV). Moreover, TG/DTA was used to analyze the thermal nature of the nanoparticle, for the determination of its thermal stability. In addition, EDAX examination revealed that the synthesized Y₂Ti₂O₇ (YTO) nanoparticle includes solely Y, Ti and O with no impurities. The biological application of Y₂Ti₂O₇ (YTO) nanoparticle was confirmed with anti-bacterial and anti-fungal activities including the zone of inhibition of organisms was dose dependently increased.
