Areas of Expertise
Dr. Jiménez’s research interests are in physical/materials chemistry, focusing on:
• Preparation and processing (e.g. solid-state chemistry, in situ techniques, laser irradiation) of novel optical materials such as nanoparticle and rare-earth doped glasses and thin films
• Optical interactions and energy transfer processes at the nanoscale (e.g., plasmonics)
• Luminescence and optical spectroscopy of solids, emphasizing amorphous systems
• Time-resolved spectroscopy and nonlinear optics
• Materials characterization and analysis (e.g. XPS, XRD, TEM, Raman)
Projects are envisioned for the design of material systems for a wide range of functional applications such as laser materials, display devices, optical data storage, telecommunications, solar cell technology, chemical sensing, antimicrobial bio-composites ,and tissue engineering. Obtaining physico-chemical insights on underlying material properties and the tailoring of such for applications are key aspects of the research.
