Structure and spectroscopy characterization of La$_{1-x}$Sm$_x$VO4 luminescent nanoparticles synthesized co-precipitation and sol-gel methods

TL;DR

This study investigates the synthesis, structure, and optical properties of Sm-activated LaVO4 nanoparticles produced via co-precipitation and sol-gel methods, highlighting how synthesis method and Sm concentration affect their characteristics.

Contribution

It provides a comparative analysis of how co-precipitation and sol-gel methods influence the structural and spectroscopic properties of Sm-doped LaVO4 nanoparticles.

Findings

Synthesis method affects nanoparticle morphology and phase composition.

Sm concentration influences crystal structure and optical spectra.

Abstract

The Sm-activated orthvanadate nanoparticles were synthesized by co-precipitation and sol-gel methods. XRD study has shown that synthesized samples are characterized by monoclinic or tetragonal structure as well as their mixture dependently on Sm concentration and methods of synthesis. Influence of method of synthesis on morphology of nanoparticles, their absorption, diffuse reflectance and emission spectra was observed and studied.
