Is there simple route of synthesizing SmNiO3?

I have learnt from the literature that SmNiO3 phase can be synthesized at high pressure (100bar of Oxygen pressure) and high temperature (770K) conditions. Though these conditions are very...

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...

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...
