Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

open access: yesAdvanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

Beta‐Lactoglobulin for Water‐Based and Tunable Nanostructure Templating of Printed Titania Thin Films: The Influence of pH Value and Protein Concentration

open access: yesAdvanced Materials Interfaces, EarlyView.
The synthesis route for the fabrication of nanostructured titania thin films focuses on water‐based solutions, abundant, nontoxic materials, and a highly scalable deposition technique. Using beta‐lactoglobulin enables tunable titania thin film templating and allows for different domain sizes, porosities, and morphologies.

The Role of Dynamic Solvent Swelling in Electrochemical Doping of Semiconducting Polymers

open access: yesAdvanced Materials Interfaces, EarlyView.
Solvent swelling in organic electrolytes dynamically evolves during electrochemical doping of poly(3‐hexylthiophene) (P3HT); multiple polymers, ranging from highly regioregular to fully regiorandom, demonstrate how crystallinity controls swelling.

Surface Properties of p‐GaN and Formation of Nickel Metal Contacts

open access: yesAdvanced Materials Interfaces, EarlyView.
The amount of C, O, and Mg–O bonds on the surface of p‐GaN can be reduced while still maintaining the surface morphology by potassium hydroxide (KOH) wet chemical treatment. Heating this surface with Ni on top in ultra‐high vacuum (UHV) results in a crystalline Ga‐Ni alloy and diffusion of Ga, which creates vacancies close to valence band leading to ...
