Multimodal Luminescence from LaAlO3:Eu3+ via Trap Modulation for High‐Temperature Applications

Advanced Photonics Research, EarlyView.
LaAlO3:Eu3+ (LAO:E) phosphor exhibiting multimode luminescence enabled by multilevel traps spanning shallow to deep states is reported. These traps ensure controlled charge storage and release at room and elevated temperatures. Experimental studies and theoretical calculations reveal the trapping–detrapping mechanism, highlighting LAO:E as a promising ...

Compression‐Induced Amorphization of ZIF‐62 Leading to Formation of Porous Glass: Overcoming the Limitations of Current Methods

Chemistry–Methods, EarlyView.
Nonhydrostatic compression in steps is applied to transform crystalline zeolitic imidazolate framework‐62 into glass at room temperature. This method overcomes the limitations of existing approaches. This research reveals the mechanism of this phase transformation, including modifications in porosity, using various techniques, particularly positron ...

Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a “Radical + Ice” Mechanism

ChemPlusChem, EarlyView.
The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...
