The LiAlSiO4:Ce3+ (0-11 mol%) nanocomposites are synthesized by low temperature solution combustion method using aloe vera gel as a fuel. The prepared samples are characterized by powder X-ray diffraction (XRD) to know the crystallite size, optical energy band gap by Kubelka-Munk (K-M) plot and surface morphology by scanning electron microscope (SEM) coupled with energy dispersive X-ray (EDX) analysis for elemental confirmation. The stretching frequency of all nanocomposites is confirmed by Fourier transform infrared (FTIR) spectra. The Raman spectroscopy provides a structural fingerprint by which molecules can be identified. The current-voltage (I-V) characteristics showed that the prepared samples obey Ohm's law. DC conductivity is studied for temperature ranging from 30-450 degrees C and activation energy is calculated by Arrhenius plot. Further, the present method was reliable, environmental friendly and alternative to economical routes.
