(a) 773 K (b) 873 K and (c) 973 K.
EDS Analysis
EDS results of ZnMn2O4 nanofibers at different calcination temperature are shown
in table S1. Theoretical values of mass and atomic percentage are compared with
that of experiment values obtained. Fig. S2 shows the EDS spectrum of ZnMn2O4
nanofibers calcined at 773 K. When the calcination temperature is 773 K the mass
and atomic percentage values are close to theoretical value. The deviation increases
as the calcination temperature is increased. So it is observed that the mass and
atomic percent of elements increases with increase in calcination temperature.
