Dear everyone. I used GSAS-II to estimate crystallite size from lab PXRD. The sample was annealed anatase. Before annealing all results (GSAS-II, Debye function analysis (DFA), GSAS and HRTEM) were the same, about 5nm. After annealing GSAS-II gave 19/21(0.3) nm, while DFA gave 14(5) nm and HRTEM gave 12(3). Does anyone got the same , what seem to be, over estimation by GSAS-II? Of course, using standard deviation give not so far results. Best regards,Victor
