Plant Mediated Synthesis of Rare Earth Ions Doped SrAl2O4 Nano Phosphors and its Luminescent Properties

Abstract

The ability of individuals to generate and manipulate things to meet their newlinerequirements has been closely linked to the development and advancement of the newlinesociety. In earlier days, the level of material development has been used to classify newlinecivilizations (Stone age, Bronze age, and Iron age). The material development aid to newlinehuman needs gets evolved day by day. In this regard, nanoscience and newlinenanotechnology are new era of materials fabrication due to its outstanding newlineadvantages. Hence numerous interest have been paid by the scientific community newlinetowards development of nanomaterials aligned with different applications. The newlinenanomaterials (NMs) serve as a link between individual molecules and infinite bulk newlinesystems. Clusters, nanoparticles, nanocrystals, quantum dots, nanowires, and newlinenanotubes are examples of individual nanostructures. The physical and chemical newlineproperties of the NMs are greatly differ from bulk counterparts. newlineTill date, numerous inorganic based NMs, such as oxides, silicates, borates, newlinefluorites, aluminates, tungstates, vanadates, etc. are explored in detailed. Among newlinethem, particularly metal oxides have been gained prominence in the realm of newlineluminescence due to their superior optoelectronic properties. They could be used as newlineefficient phosphors in flat panel displays, solar energy converters, optical amplifiers, newlineelectroluminescent devices, photodiodes, bio-detectors, lamp industries, radiation newlinedosimetry, and color display, among other applications. As of today, strontium newlinealuminates are also considered as one of the best host material because of their newlinestable crystal structure, high physical and chemical stability, long persistence time newlineand good formability. newlineSeveral efforts have been made to synthesize nano-sized phosphors by newlinedifferent routes namely, hydrothermal, sol gel techniques, co-precipitation, solid newlinestate method, molten salt, spray pyrolysis, combustion routes, etc. The use of toxic newlineand volatile solvents/chemicals during the synthesis of the NMs followed by newlinetraditional routes may cause environmental an
