Raman spectroscopy of crystals for stimulated Raman scattering

Spectroscopy of tetragonal Eu:NaGd(WO4)2 crystal

“…In addition, for NGW, particularly this crystal cut is beneficial in terms of weaker thermo-optic effects [49]. Both monoclinic and tetragonal DTs are well-known Ramanactive media [50,51] also offering the possibility of self-Raman conversion [52]. Raman spectra of Eu:NGW are shown in Fig.…”

Síntese pelo método da coprecipitação e caracterização estrutural do tungstato de cálcio com estrutura tipo scheelita

“…Pode-se afirmar que há extrema consonância entre os resultados deste trabalho e os outros já publicados, ou seja, , os modos vibracionais visualizados no espectro Raman de molibdatos podem ser classificados em dois grupos: modos internos e modos externos [31,32]. No espectro vibracional na região do infravermelho, dois modos acústicos (1A u e 1E u ) são inativos enquanto que os modos ópticos B u são proibidos.…”

Electrical and Vibrational Studies of Na2K2Cu(MoO4)3

“…The correlation between the point group of symmetry of the free anion MoO 4 , its site-symmetry 1 , and its factor group is represented in Scheme 1. According to Basiev et al [34], the vibrational modes observed in Raman spectra of molybdates can be classified into two groups, internal and external modes. The internal vibrational modes of each type of MoO 4 derived from the correlation scheme are equal to (3 − 6) = 18, where is the number of atoms in the molecular MoO 4 :…”
