“…A blue emitting phosphor, Sr 2 CeO 4 , has therefore been synthesized by combinatorial material synthesis by Danielson et al [2]. Subsequently other synthesis techniques like solid state reaction [3], chemical co precipitation process [4], microwave calcination technique [5], ultrasonic spray pyrolysis technique [6], pulsed-laser deposition procedure [5,7], Pechini's method [8], citrate-gel method [9], combustion method [10], microwave-accelerated hydrothermal technique [11], polymer synthesis [12], wet chemical method [13], emulsion liquid membrane system [14,15], sol-gel by single alkoxide precursor [16], laser ablation [17], microemulsion method [18] and carbonate precursor [19] have been tried to synthesize the same material. Some of the above techniques requires higher firing temperature, i.e.…”
