Photoluminescence Turn‐On Method to Determine the Kinetics of Thermally Activated Delayed Fluorescence Materials

open access: yesAdvanced Physics Research, Volume 5, Issue 4, April 2026.
Thermally Activated Delayed Fluorescence (TADF) is widely exploited to achieve high‐efficiency OLEDs. TADF Emitters are normally investigated with transient photoluminescence (PL), which requires the PL to be detected over multiple orders of magnitude in time and intensity.

Interactions Between O‐Phospho‐L‐Serine and Trivalent Metal Ions: Studies in Solution and Solid State

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 10, 1 April 2026.
The interaction between the phosphorylated amino acid O‐phospho‐L‐serine and trivalent ions of f‐elements such as La3+, Eu3+, and Lu3+, supplemented by Y3+, has been studied in aqueous media. Nuclear magnetic resonance (NMR) spectroscopy in solution and in the solid state examined complex formation from the ligand perspective, while time‐resolved laser‐

Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

open access: yesHigh Voltage, Volume 11, Issue 2, Page 458-471, April 2026.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.

Breakdown and Discharge Characteristics of High Repetition Frequency Nanosecond Pulsed Air Dielectric Barrier Discharge

open access: yesHigh Voltage, Volume 11, Issue 2, Page 445-457, April 2026.
ABSTRACT This study explores the breakdown characteristics and discharge modes in a parallel plate air dielectric barrier discharge system using repetitive nanosecond pulses, with pulse repetition frequencies (PRFs) from 0.1 to 100 kHz. It examines how pulse parameters—PRF, pulse number and gas pressure—affect the memory effect, leveraging current and ...

Analysis of Stochastic Nature and Shock Wave Pressure of Pulsed Spark Discharge in Saline With Auxiliary Pre‐Electrolysis Pulse

open access: yesHigh Voltage, Volume 11, Issue 2, Page 472-481, April 2026.
ABSTRACT Intravascular lithotripsy through liquid‐phase discharge is of great significance in improving the success rate of intravascular stent placement and treatment of severely vascular calcific plaque lesions. However, pre‐breakdown delay in intravascular lithotripsy system discharge has strong stochastic nature for the same high voltage discharge ...
