By a News Reporter-Staff News Editor at Energy Weekly News -- Research findings on Anions are discussed in a new report. According to news reporting originating in Kolkata, India, by VerticalNews journalists, research stated, "We herein report a simple and effective soft template mediated synthesis protocol for the room temperature preparation of highly crystalline cerium (Ce3+) and terbium (Tb3+) doped lanthanum phosphate (LaPO4) nanorods (NRs) and nanoflowers. Anionic surfactant sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/n-alkane soft template was chosen since it forms stable reverse micelles (RMs)."
The news reporters obtained a quote from the research from Jadavpur University, "Transmission electron microscopy (TEM) analysis corroborated successful formation of LaPO4:Ce3+,Tb3+ NRs having different aspect ratios (ranging from 2.8:1 to 7.6:1) under varying reaction conditions. The crystalline nature of the nanomaterials (NMs) was ascertained by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), and small-area electron diffraction (SAED) studies. Energy-dispersive X-ray (EDX) and Fourier transform infrared (FTIR) spectroscopy further verified the elemental existence of the desirably synthesized nanostructures. Experimental results from thermogravimetric-differential thermal analysis (TG-DTA) revealed thermal stability of the NRs up to 800 degrees C. The prepared NRs exhibit strong yellowish-green photoluminescence (PL) at 544 nm (D-5(4) ? F-7(5)) when excited at 270 nm."
According to the news reporters, the research concluded: "Furthermore, time-resolved decay analysis along with steady-state PL measurements indicated an efficient energy transfer (ET) phenomenon between Ce3+ and Tb3+ ions doped in LaPO4 (LAP) host matrix."
