Realization of effective energy transfer and color tunability between Tb3+ and Eu3+ ions in LaAlO3 host for LED display applications

Green emission from trivalent cerium doped LaAlO3/MgO nano-composite for photonic and latent finger printing applications

“…S. Kozuka et al , I. S. Silveira et al , D. Singh et al , M. Beheshti et al have reported it to be rhombohedral whereas authors such as P. Kumar et al , E. B. Shaik et al and P. Ankoji et al have reported it to be belonging to later space group having primitive cubic structure. 32–38 LAO is known to transit from rhombohedral to primitive structure around 800 K. 39 So, at room temperature its XRD should be ascribed to rhombohedral space group. To ascertain the same, Rietveld refinement of diffractograms using both the space groups have been performed and displayed in Fig.…”
