How increased photocatalytic activity can be related with increased crystallite size and decreased dislocation density by increasing dopant content?

I have doped bismuth in place of cerium ions in my composites and my xrd results show constantly increasing crystallite sizes by increasing bismuth concentration. Similarly, increased cell volume...

Band gap of complexes having more than one lambda max?

For the metal complexes I have UV-Vis spectra showing various peaks (most cases 2 peaks). Now I want to calculate bandgap using Tauc plot. My question is that using this equation I get two values...

Shifting of XRD peaks by addition of dopant in perovskites

Doped metal perovskites have been synthesized but the dopant has shifted the XRD peaks to lower theta value and crystallite size has also increased by addition of dopant. The dopant and host metal...
