Propiedades ópticas

Los métodos ópticos de caracterización han sido desde el principio fundamentales en el estudio de la materia, el desarrollo de la astronomía y de la teoría cuántica. Estos métodos son en general no destructivos y relativamente económicos, pues en el …

Lattice damage in 9-MeV-carbon irradiated diamond and its recovery after annealing

*Carbon* **123**, 334--343 (2017)

Micro-Raman spectroscopy of near-surface damage in diamond irradiated with 9-MeV boron ions

We have studied the near-surface damage in a diamond crystal caused by irradiation with swift boron ions and its healing after high-temperature annealing. A diamond crystal was irradiated with 9-MeV $^{11}$B$^{3+}$ ions with fluence values between $1 …

The apparent variability of silkworm (Bombyx mori) silk and its relationship with degumming

As spun silkworm (*Bombyx mori*) silk fibers were compared in terms of their tensile behavior and microstructure with fibers subjected to different degumming treatments. Fibers were initially retrieved by forced silking directly from the worms and, …

Laser heating induced phase changes of VO$_2$ crystals in air monitored by Raman spectroscopy

We have studied the effect of intense visible light on vanadium dioxide crystals in air by measuring micro-Raman spectra for increasing laser powers. A laser wavelength of 632.8 nm was used. For power densities above 500 MW/m2 laser heating triggers …

Differences in n-type doping efficiency between Al- and Ga-ZnO films

A careful and wide comparison between Al and Ga as substitutional dopants in the ZnO wurtzite structure is presented. Both cations behave as n-type dopants and their inclusion improves the optical and electrical properties of the ZnO matrix, making …
