Can we quantitatively estimate the volume fraction of crystalline phase (SrSiO3) and glassy phase (Na2Si2O5) by Raman analysis in synthesized sample?

We have synthesized Na doped SrSiO3 using solid state reaction method. Since XRD indicate only crystalline phase and there is possibility of glassy phase (Na2Si2O5) formation along with...

How can I evaluate a Raman mode (386cm-1) for LaInO3 at 386cm-1 is symmetric or antisymmetric stretching vibration?

I have synthesized Ca-doped LaInO3 system. From the Raman analysis, I found the highest intensity peak at 386cm-1 which is due to In-O-In streching mode. How can I know that it is a symmetric or...

In XRD, why does the sharpness of (200) and (020) planes in LaGaO3 suddenly diminish with Ca doping?

CaO is doped at La site in LaGaO3 using solid state reaction method. During powder XRD analysis, the undoped sample (LaGaO3) was matched with ICDD card 01-089-7833 and it consist of sharp peaks...

Why is there a difference between the initial value of conductivity in DC measurement and conductivity value during AC measurement?

I am trying to measure DC and AC conductivity of Ca doped LaInO3 samples and wish to separate the electronic from the ionic contribution. I assume that initial value of conductivity in DC...

Does gold sputtering in electrolyte samples (disc-shaped) interfere during AC conductivity measurements?

I used gold sputtering (to make electrode contacts) in Ca doped LaInO3 samples for AC conductivity measurement from room temperature to 800C. Does it interfere with the conductivity response of my...

Why is red shift in raman bands from 180-300cm-1 obtained when Ca is doped in LaInO3 perovskite?

Ca doped LaInO3 samples were synthesized using solid state reaction method. 5mol%Ca shows maximum red shift(3cm-1) for 180cm-1 band. With further doping, lesser red shift is obtained. Also, The...
