1. Towards single Ce ion detection in a bulk crystal for the development of a single-ion qubit readout scheme
Abstract : The work presented in this thesis was concerned with investigating the relevant spectroscopic properties of Ce ions randomly doped in an Y2SiO5 crystal at low temperatures (around 4 K), in order to develop a technique and an experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion) can be used as a local probe to sense the quantum state of a neighbouring single-ion qubit via a state-selective interaction between the readout and qubit ion.

2. Photonic crystals and photocatalysis : Study of titania inverse opals
Abstract : Due to an increase of human activity, an increase health risk has emerged from the presence of pollutants in the environment. In the transition to renewable and sustainable life style, treatment of pollutants could support the shifting societies. READ MORE

3. Radiative Properties of Rare Earth Elements - Free and Bound in Crystals
Abstract : This thesis is devoted to fundamental aspects, and to spectroscopic applications of radiative properties in free atoms and ions, as well as in ions doped into crystals. Using the time-resolved laser-induced fluorescence technique, measurements of radiative lifetimes for rare earth elements have been performed in neutral Pr, Nd, Tm, and in singly ionized Sm, Er, Nd, Tm, Yb, as well as in doubly ionized Tm and Tb ions.

4. Ellipsometric studies of SiC in the infrared, visual and ultraviolet spectral region
Abstract : Spectroscopic ellipsometry has been used to determine the dielectric function of the most common polytypes, 3C, 4H and 6H, of SiC and also of some related materials. Measurements have been performed in the infrared, visible and ultraviolet energy region. READ MORE

5. Hypothermia and radiation. Effects on DNA, chromatin and cellular survival
Abstract : The effect of ionising radiation on cells can be modulated by several physico-chemical factors. The aim of this study was to investigate if hypothermic (sub-physiological) temperatures (2°C-28°C) may influence the effect of X-rays on cellular damage in human normal fibroblasts and in a human breast adenocarcinoma cell line, MCF-7.
