Overcoming the Short‐Wave Infrared Barrier in the Photoluminescence of Amino‐As‐Based InAs Quantum Dots

open access: yesAdvanced Optical Materials, EarlyView.
A novel reducing agent, trioctylamine‐alane (TOA‐AlH3), is reported for the synthesis of amino‐As‐based colloidal InAs quantum dots (QDs). The use of TOA‐AlH3 in an ad‐hoc seeded‐growth method with ZnCl2 as an additive delivers InAs QDs with narrow size distributions and excitonic absorption extending up to 1300 nm. ZnSe shelling leads to InAs@ZnSe QDs

Evolution of Collective, Radiative Plasmon Coupling in Confined, Soft Colloidal Films

open access: yesAdvanced Optical Materials, EarlyView.
Plasmon resonance coupling is continuously monitored during the uniaxial manipulation of a 2‐dimensional soft colloidal film containing hexagonally arranged spherical gold nanocrystals. This is realized by the in situ spectroscopic investigation of a monolayer of plasmonic core‐shell microgels confined at the air/water interface that is compressed in a

Simple and Environmentally Friendly Solution Synthesis of CsPbI3 Nanoribbons: Investigating the Reversible δ‐ to γ‐Phase Transition

open access: yesAdvanced Photonics Research, EarlyView.
Cesium lead iodide (CsPbI3) nanoribbons obtained through mild condition synthesis are herein reported without surfactant species and toxic solvent starting from β‐diketonate complexes of Cs and Pb. The morphological and structural features, together with the thermal stability and phase transitions from the yellow δ to the black α and γ‐CsPbI3 phases ...

Comparison of Glass Material and Laser Excitation Regime for Upconversion‐Based 3D Volumetric Display

open access: yesAdvanced Photonics Research, EarlyView.
This study explores scalable glass matrices for two‐step, two‐frequency (TSTF) upconversion‐based 3D volumetric displays. While Er3+‐doped TeO2–ZnO–Na2O (TZN) and BaO–Ga2O3–GeO2 (BGG) glasses show weaker TSTF upconversion than reference ZrF4–BaF2–LaF3–AlF3–NaF (ZBLAN) glass under continuous‐wave lasers, TZN surpasses ZBLAN under pulsed laser excitation

Recent Progress in Strategies to Enhance the Spin‐Orbit Coupling of Multiresonance Thermally Activated Delayed Fluorescent Materials for Narrowband Organic Light‐Emitting Diodes

open access: yesAdvanced Photonics Research, EarlyView.
For multiresonance thermally activated delayed fluorescent emitters, the reverse intersystem crossing (RISC) process is of paramount importance. This review summarizes two approaches to enhance the RISC rate by improving spin‐orbit coupling: the heavy atom strategy and the long‐range charge‐transfer/short‐range charge‐transfer strategy.
