Structural, luminescence and Judd-Ofelt analysis to study the influence of post-annealing treatment on the AIN:Tb thin films prepared by radiofrequency magnetron sputtering
(Pontificia Universidad Católica del PerúPE, 2016-06-20)This thesis investigates the effects of the annealing treatments on the spontaneous emission, radiative lifetime, composition and structure of terbium doped aluminum nitride films deposited on silicon substrates by radio ... -
Synthesis and characterization of nanostructured ternary MAX-phase thin films prepared by magnetron sputtering as precursors for twodimensional MXenes
(Pontificia Universidad Católica del PerúPE, 2023-03-07)MAX phase thin films can be fabricated through firstly depositing a precursor thin film consisting of the initial elements M, A, and X close to the MAX phase stoichiometry employing physical vapor deposition techniques ... -
Synthesis and characterization of new pH- and thermo-responsive hydrogels based on N-isopropylacrylamide and 2-oxazolines
(Pontificia Universidad Católica del PerúPE, 2022-04-28)New pH- and thermo-responsive hydrogels (HG) were synthesized by free radical polymerization of N-isopropylacrylamide and a macromonomer, which was a hydrolyzed random copolymer of 2-carboxyethyl- and 2-methyl-2-oxazoline, ... -
Synthesis and characterization of wide bandgap semiconductors doped with terbium for electroluminescent devices
(Pontificia Universidad Católica del PerúPE, 2016-06-20)In this work, stoichiometric, structural and light emission properties of amorphous wide bandgap semiconductor materials doped with terbium are presented. The amorphous nature of the thin films was confirmed by X-ray ... -
Synthesis of Hydroxyapatite thin films on PMMA Printed Substrates
(Pontificia Universidad Católica del PerúPE, 2018-01-19)Each year millions of people suffer from bone defects resulting from trauma, tumors or bone-related injuries. Therefore there is a need to continuously develop new materials or improve the properties of the materials ... -
Synthesis of silver nanoparticles in hydrogels
(Pontificia Universidad Católica del PerúPE, 2018-04-16)The present work is concerned with the fabrication of a novel hydrogel-silver hybrid material, the characterization regarding its structural and antibacterial properties and the investigation of its interaction with glass ... -
Synthesis, characterization and corrosion resistance of electroless Ni-P and Ni-P-SiC coatings: a comparative study
(Pontificia Universidad Católica del PerúPE, 2019-08-06)Electroless Ni-P coatings have been widely used due to their good combination of properties such as hardness, wear resistance and corrosion resistance. The addition of dispersed hard micro-particles into the Ni-P matrix ... -
Utilización de una Nariz Electrónica elaborada a partir de MOS para la evaluación y diferenciación de la calidad del pisco peruano
