Surface Oxidation of 2D γ‐Indium Sulfide Nanoplatelets and Its Impact on Photoluminescence

open access: yesAdvanced Photonics Research, EarlyView.
Photoluminescence of defective 2D γ‐In2S3 can be modulated after exposure to air or oxygen‐containing ligands. Cryogenic photoluminescence measurements reveal that a new acceptor level is introduced upon oxidation, modulating the relative intensity of the emission bands.

High‐Resolution On‐Chip Digitally Tunable Spectrometer Based on Double‐Cascaded Ring Resonators

open access: yesAdvanced Photonics Research, EarlyView.
An integrated spectrometer is here presented, based on two cascaded ring resonators covered with a phase change material. The Vernier architecture is implemented allowing for a digital scan of wavelengths. Resolution smaller than 0.1 nm can be achieved, together with a footprint ≈0.03 mm2 and a bandwidth of the order of tens of nanometers.

Structure and Electrochemical Properties of ReS2‐LaFeO3 Nanocomposite for Dopamine Sensing

open access: yesAdvanced Sensor Research, EarlyView.
A novel ReS2‐LaFeO3 nanocomposite is developed for sensitive and reliable detection of dopamine (DA), an important neurotransmitter. The material performs well even in complex biological samples, demonstrating strong selectivity and accuracy. These findings highlight its potential for future applications in medical diagnostics and neuroscience research.
