Wireless Nano Irradiance Meter Based on Upconversion Luminescence Lifetime

open access: yesAdvanced Optical Materials, EarlyView.
A wireless nano irradiance meter is developed based on upconversion nanoparticles that enabled local readouts through their luminescence lifetime. This method allows for remote and precise light irradiance quantification in complex media, offering significant potential for light‐based technologies such as photodynamic therapy and nanothermometry ...

Thermal Emission of Strontium in a Cryogenic Buffer Gas Beam Source [PDF]

open access: yesarXiv
We demonstrate production of cold atomic strontium (Sr) and strontium-containing molecules (SrOH) in a cryogenic buffer gas beam source via direct heating of strontium oxide (SrO) with 30 mJ laser pulses several milliseconds long. $3.7(2)\times10^{14}$ Sr atoms are released, which represents a factor of 7 increase in atomic production per pulse ...

High Sensitivity Spin Defects in Carbon Implanted Diamond

open access: yesAdvanced Optical Materials, EarlyView.
Self‐interstitial spin defects in diamond are fabricated in diamond by high energy carbon irradiation. Along with a systematic characterization of their properties, these spin defects demonstrate high sensitivities surpassing previous studies and coherent manipulation of spin states.

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters

open access: yesAdvanced Optical Materials, EarlyView.
Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.

Mechanoluminescence of Bi‐Activated NaYGeO4 Polycrystals and 3D Printed Scaffolds in the NUV/Blue and NIR Spectral Range

open access: yesAdvanced Optical Materials, EarlyView.
NUV/Blue and NIR emitting mechanoluminescent (ML) materials based on a Bi‐doped germanate compound (NYGOBx) are reported. 3D‐printing is used to fabricate complex scaffold devices from this material, suggested for use as mechanically‐activated light sources for functional illumination.
