Ten deep blue to cyan emission lines from an intracavity frequency converted Raman laser
(Society of Photho-optical Instrumentation Engineers, 2016)
Raman spectroscopy applied to molecular transformation of photochromic polymers
(2012-12-17)
Photochromic polymers are materials with high potential for applications in optical devices. In this work we
analyzed the polymeric matrix effect in convertion and reconvertion efficiency of spiropyran trough Raman
spectroscopy ...
Otimização de amplificadores híbridos RAMAN+EDFA utilizando reciclagem de bombeamento
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2010-11-30)
In this work different configurations of hybrid amplifiers are studied, made by a Raman amplifier followed by an EDFA. Such amplifiers can be used to increase the transmission capacity in WDM based optical communication ...
The investigation of α→β phase transition in poly(vinylidene fluoride) (PVDF)
(2005-12-01)
The phase transition from the non-polar α-phase to the polar β-phase of poly(vinylidene fluoride) (PVDF) has been investigated using micro-Raman spectroscopy, which is advantageous for being a non-destructive technique. ...

Studies on the resonance Raman spectra of polyaniline obtained with near-IR excitation
(JOHN WILEY & SONS LTD, 2008)
The effects of near-IR (NIR) laser power over the Raman spectra of poly(aniline) emeraldine salt (PANIES) and base (PANI-EB) were investigated. The reasons for the existence of several bands from 1324 to 1500 cm-1 in the ...
