Spin‐Valley Polarization Control in WSe2 Monolayers using Photochemical Doping

open access: yesAdvanced Optical Materials, EarlyView.
A photochemical doping method is employed to modulate the spin‐valley polarization in WSe2 monolayers by tuning the carrier density from electron‐rich to hole‐rich regimes. This controlled doping enables a three‐fold variation in exciton polarization, revealing relaxation channels driven by scattering between excitons and charge carriers in two ...

Bright LaF3:Eu@Ir Phosphors Combining Two‐Photon Excitation, d → f Energy Transfer and Tunable Time‐Gated Chromaticity for Multicolor Cell Imaging

open access: yesAdvanced Optical Materials, EarlyView.
The surface functionalization of Eu‐doped LaF3 particles with a two‐photon absorbing IrIII complex results in the formation of ultrabright Eu:LaF3 phosphors, which exhibit a combination of short‐lived IrIII and long‐lived EuIII‐sensitized emissions. These Ir/Eu hybrids are effectively internalized by HEK‐293 cells without causing toxic effects, thereby

Triplet–Triplet Annihilation Photon Upconversion Toward UVC Energy Generation Using TIPS‐Benzene and a Heptazine Derivative

open access: yesAdvanced Optical Materials, EarlyView.
The TTA‐UC from visible/UVA to UVB/C is demonstrated by combining a heptazine derivative with TIPS‐benzene‐based emitters. The heptazine derivative has a triplet energy level high enough to sensitize the emitters. The introduction of bulky tert‐butyl substituents to the TIPS‐benzene emitter is a simple and powerful strategy for enhancing the TTA‐UC ...
