Overview

Randomized trial investigates optical properties in La2AlCoO6, suggesting phosphor material for white light emission.

Key Points

  • This research aims to synthesize and characterize La2AlCoO6 double perovskite to explore its thermal and optical properties.
  • Synthesis via sol-gel technique and calcination at 600 to 900 °C
  • Analysis using thermogravimetry, X-ray diffraction, FTIR, EDX, and XPS
  • Evaluation of optical properties through UV-visible and photoluminescence spectra
  • Thermal stability observed with initial weight loss of 7% below 250 °C and 50% between 300 °C and 700 °C
  • Crystallite size increased from 21 nm to 24 nm with higher calcination temperature
  • High absorbance in UV region with optical band gap ranging from 2.6 to 3.03 eV and good white light emission properties.
