| dc.description.abstract | A characterization of the optical properties of three crystalline lutetium garnets doped with trivalent neodymium 𝑁𝑑3+ luminescent ions has been carried out. For this purpose, steadystate optical spectroscopy has been used to measure the absorption and luminescence spectra, as well as time-resolved spectroscopy to calculate the lifetimes of the excited states of the 𝑁𝑑3+ ions in 𝐿𝑢3(𝐺𝑎𝑥𝐴𝑙1−𝑥)5𝑂12 garnets. It has also been measured how the luminescence changes with temperature, in order to calibrate a low-temperature optical sensor. Furthermore, an experimental equipment has been developed to determine the pressure in the sample’s chamber of a diamond anvil cell. | en |
