Femtosecond Laser in Polymeric Materials: Microfabrication of Doped Structures and Micromachining
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
The use of laser light to modify the material's surface or bulk as well as to induce changes in the volume through a chemical reaction has received great attention in the last few years, due to the possibility of tailoring ...
Influence of laser excitation on raman and photoluminescence spectra and FTIR study of porous silicon layers
(Sociedade Brasileira de Física, 1999)
A porous silicon lm (PS) was investigated by FTIR, Raman and photoluminescence (PL) spectroscopies. The Raman and PL spectra were obtained using four different laser excitations: 488, 514, 633 and 782 nm. The analysis of ...
