UV–Vis spectra indicated a decrease in the optical band gap values with an increase in x content in the (Ba1-xSrx)MoO4 ceramics. PL emissions exhibit a non-linear behavior to increase or decrease with the increase of Sr2? ions in the tetragonal lattices, when excited by a wavelength of...
Resonance Raman spectra of pyridoxal 5′-phosphate and salicylaldehyde Schiff bases of amino acids in H2O show the presence of the -C=NH+ bond. This proves that the predominant resonance form of the tautomer is the protonated imine. The tautomer of aryl Schiff bases in less polar solvents exis...
Owing to the physical mechanism at their basis, Raman spectra are sensitive to any change in the material that alters the energy of optical phonons, like the breaking or formation of chemical bonds, phase transitions, residual strain/stress, or the presence of lattice defects. One of the ...

This paper reports the polarized Raman spectra of Sr_(0.51) Ba_(0.39) Nb_2O_6 with different Cd doping contents at different temperature. With the increasing of temperature and doping contents, the width of the bands broadened while the intensities of peaks decreased. But no obvious changes ...
The temperature on the sample at the laser spot was estimated based on the ratio of the Stokes and anti-Stokes intensity in the Raman scattering spectra, which were excited by an He–Ne laser beam with power densities ranging from 103 to 104 W cm2. The estimated temperatures show that the...
