Abstract

This paper reports the detailed preparation of strontium aluminate phosphors (SrAl2O4) by solution combustion method using respective metal nitrates and oxalyline dihydrazine as a fuel. It results in low density, voluminous mass compared to the samples prepared by other conventional methods. The present work reports the changes made in combustion process to achieve homogeneous nano powder in large scale with a short interval of time. The sample has been characterized by X- ray diffraction studies, scanning electron microscopy, TG/ DTA, FTIR and UV-Visible. XRD result shows the sample is in monoclinic phase. Scanning electron microscope reveals the product is highly voluminous and porous in nature. The size of the particles was about 100 nm. In FTIR transmittance peaks observed at 3744 and 1471 cm-1. The band gap comes out to be 5.18ev
