Notes:
The objective of this work is to present the results of the comparative analysis ofYAG:Ce3+ microstructural parameters obtained from x-ray powder diffraction (XRPD) data usingRietveld based Koalariet and Fullprof programs. YAG:Ce3+ powder is obtained via lowtemperature aerosol route at 3200C followed by post annealing treatment. The chosen technique ofsynthesis, i.e. ultrasonic spray pyrolysis, provides the generation of spherically shaped andsubmicronically sized particles having composite nanostructure. Since the targeting garnet phaserepresents a very promising host phosphor material being doped with rare-earth ions, the mostimportant criteria determining its applicability in various optical devices is the uniform distributionof the luminescent center in the host lattice as well as the cubic YAG phase crystallinity.Comparison of the data obtained for the same samples by the above mentioned XRPD analysesgives us an insight into the validity of the refined parameters
