Abstract: The present invention relates to the synthesis of europium-doped strontium magnesium germanate phosphors and, in more particular manner, to a process for the synthesis of Sr2MgGe2O7:xEu3+ (SMGO:xEu3+) phosphors (where x=0.5-6 mol %) for white LEDs, latent fingerprint detection, and anti-counterfeiting applications. The synthesis is carried out by mixing Stoichiometric molar amounts of strontium nitrate (Sr(NO3)2), magnesium nitrate (Mg(NO3)2·6H2O), germanium dioxide (GeO2), and europium nitrate (Eu(NO3)3·6H2O) were dissolved in deionized water, and further adding Aloe vera gel extract as a natural fuel, wherein the resultant solution is stirred to obtain a homogeneous redox mixture, which then boiled, ignited to form a gel, and combusted into a fine powder, wherein the fine powder is then annealed for improve crystallinity.
