doi:10.33263/briac126.71477158

Abstract

This paper reports the structural, morphological, and antibacterial studies of ZrO2:Tb3+ nanophosphors (NPs). The ZrO2:Tb3+ NPs were synthesized by hydrothermal route using Amylamine as surfactant. ZrO2:Tb3+ nanophosphors was characterized by Powder X-ray Diffraction(PXRD), Scanning Electron Microscope (SEM),Diffuse reflectance spectroscopy (DRS), Photoluminescence(PL), Raman spectra, Fourier Transform Infrared radiation(FTIR) and Transmission Electron Microscope(TEM). PXRD analysis shows better crystallinity, cubic in-phase and good homogeneity of the synthesized phosphors were confirmed. When the Tb3+ concentration varies, we obtain blue emissions from ZrO2:Tb3+ NPs. ZrO2:Tb3+ NPs have a promising approach to blue light sources in the display application. SEM images show that ZrO2:Tb3+ nanophosphors have good morphology with a nonporous structure. TEM and SAED pattern confirms that ZrO2:Tb3+ nanophosphors are crystalline in nature. ZrO2:Tb3+ (9mol %) nanophosphors possessed a good antibacterial ability.

Highlights

The significance of nanophosphors in the field of research has been hugely developed because of their optical property [1]
The resulting reaction mixture was added to a Teflon-lined stainless steel autoclave of 300 ml, filled with 80% solvent constituted by 60 % double distilled water and 20% Amylamine, which acted as a surfactant [22]
The PXRD patterns of ZrO2:Tb3+ (1−9mol %)NPs are shown in fig

Summary

Introduction

The significance of nanophosphors in the field of research has been hugely developed because of their optical property [1]. They were broadly utilized in display applications [2], luminescent security ink [3], solar cell applications[4], bioimaging[5],photonic applications[6], etc. ZrO2 is nanophosphors exists in three crystalline phases at different temperature, i.e., cubic phase(>2640K), tetragonal phase(1440-2640K) and monoclinic phase(
