     <dcterms:abstract xml:lang="fr">Dans cette thèse, la synthèse, les propriétés et les applications de verres contenant des quantum dots (QDs) de chalcogénure ont été étudiées. Des verres contenant des QDs à base de chalcogénure de plomb (PbSe ou PbS) ont été préparés. Leurs propriétés optiques et leurs applications potentielles ont été explorées en combinaison avec le co-dopage aux ions Tm3+. De plus, sur la base de ces résultats, des verres contenant des QDs de ZnS ou de ZnSe, sans plomb, ont été préparés avec succès. Leurs performances luminescentes ont été encore améliorées par dopage avec des ions de métaux de transition représentés ici par le nickel. Ces résultats jettent les bases pour l’amélioration des propriétés optiques de verres contant des QDs à base de chalcogénure de plomb et aussi pour le développement de verres aux QD sans métaux lourds et donc plus respectueux de l’environnement. Bien que des améliorations futures soient possibles et nécessaires pour des applications réelles, ces verres aux QDs de chalcogénure, développés dans ce travail, présentent un potentiel d'applications dans les domaines des concentrateurs solaires luminescents, de l'anti-contrefaçon optique, de l'éclairage à semi-conducteurs et de la mesure optique de la température.</dcterms:abstract>
     <dcterms:abstract xml:lang="en">In this dissertation, the synthesis, properties and applications of glasses containing chalcogenide quantum dots (QDs) have been studied. Multicomponent lead chalcogenide QDs glasses (containing PbSe or PbS QDs) were successfully prepared, and their optical properties and potential applications were explored in combination with rare earth Tm3+ ion doping. In addition, based on the results, lead-free and environmentally friendly chalcogenide QDs glasses (containing ZnS or ZnSe QDs) were successfully prepared, and its luminescent performance was further improved by doping with transition metal nickel ions. These results lay the foundation for the improvement of optical properties of lead-based chalcogenide QDs and for the development of environmentally friendly heavy metal-free chalcogenide QDs glasses. Although future improvements are possible and necessary for practical applications, these chalcogenide QDs glasses developed in this work have application potential in the fields of luminescent solar concentrators, optical anti-counterfeiting, solid-state lighting, and optical temperature sensing.</dcterms:abstract>
