Figure 2.
The image shows a graph plotting two variables, F H W M in degrees on the left vertical axis and crystalline size in nanometres on the right vertical axis, against temperature in degrees Celsius on the horizontal axis. The black line represents F H W M as a function of temperature, decreasing from approximately 1 degree at 280 degrees Celsius to about 0.4 degrees at 380 degrees Celsius. The blue line represents crystalline size, starting at approximately 11 nanometres at 280 degrees Celsius and rising to approximately 18 nanometres at 380 degrees Celsius. Both axes are clearly labelled, with a marked arrow indicating the range of temperature. The graph highlights the inverse relationship between F H W M and crystalline size as temperature increases.Crystalline size and FHWM plotted against the annealing temperatures
