Synchrotron-Assisted HPHT Annealing Of Quantum Nanodiamonds: In Situ Control Of Phase Stability

Group-IV color centers in nanodiamond, such as silicon-vacancy (SiV) defects, are promising quantum emitters for sensing and photonics due to their bright and narrow zero-phonon line (ZPL) emission, representing up to 80% of their total luminescence…

High-pressure high-temperature annealing of quantum nanodiamonds: in situ synchrotron investigation of nanoscale graphitization and optical quality

Color centers in nanodiamonds are promising solid-state quantum emitters for sensing and quantum technologies. However, nanodiamonds often exhibit significant lattice strain and structural disorder, which degrade their optical properties and limit…

Investigating the effects of Ag/Au nanoparticle mixing ratios on nonlinear optical properties using femtosecond laser light

This study investigates the nonlinear optics (NLO) characteristics of colloidal silver–gold (Ag/Au) nanoparticles (NPs), synthesized in varying mixing ratios under femtosecond laser excitation. We show how to create Ag/Au NPs using a two-step…

About Carrier's Self‐Trapping and Dynamical Rashba Splitting in the 2D Hybrid Perovskite (BA)<sub>2</sub>(MA)<sub>2</sub>Pb<sub>3</sub>l<sub>10</sub>

Time‐ and Angle‐Resolved Photoelectron Spectroscopy (tr‐ARPES) is employed to monitor photoexcited electrons in the 2D hybrid perovskite (BA)2(MA)2Pb3l10. Photoelectron intensity maps are in good agreement with ab‐initio calculations of the band…

Fluorescent Nanodiamond-Based Delivery Systems for Mitochondrial Targeting of Bioactive Peptides

Mitochondria are recognized as key players affecting hallmarks of oncogenesis, tumor progression, and chemotherapy resistance, positioning this organelle as an important therapeutic target. We previously demonstrated that impairment of the AIF…
