Optical and luminiscent properties of terbium / ytterbium doped aluminum oxynitride and terbium doped aluminum nitride thin films
(Pontificia Universidad Católica del Perú, 2020-08-06)
In the present thesis the optical and light emission properties of two systems consisting of Tb3+ and Yb3+ doped amorphous AlOxNy thin films and Tb3+ doped polycrystalline AlN thin films were analyzed. In the two ions system, ...
Preparación y optimización de películas delgadas de sistemas de carbono-sílice dopados con tierras raras para aplicaciones luminiscentes
(Pontificia Universidad Católica del Perú, 2022-02-01)
El uso de elementos de tierras raras (RE) en materiales de luminiscencia ha permitido
introducir mejoras en diversas aplicaciones. En iluminación, por ejemplo, los fósforos
amarillos YAG (Y3Al5O12:Ce3+) son ampliamente ...
Synthesis, tribology, electro-tribology and mechanical performance of ti2alc and ti3alc2 max phases thin films
(Pontificia Universidad Católica del Perú, 2023-01-26)
This thesis investigates the synthesis, mechanical properties, tribological and electro-tribological
behavior of Ti2AlC and Ti3AlC2 MAX phases in the form of thin films. The thin films were obtained by
deposition of a ...
