Polarization‐Dependent Multiphoton‐Excited Self‐Trapped Emission in Alloyed 0D Rb7Bi3Cl16 Metal Halides via Sb3+ Doping

open access: yesSmall Science, EarlyView.
The zero‐dimensional metal halides Rb7Bi3Cl16 can achieve a transition from non‐luminescence to effective polarization‐dependent multi‐photon STEs emission after Sb3+ ion doping. The mechanism of high‐efficiency STEs in doped Rb7Bi3Cl16 is the non‐radiative recombination was suppressed, whose lifetimes changed from 93.9 ps to 3.6 ns after doping Sb3 ...

Breaking the Low Concentration Barrier of Single‐Molecule Fluorescence Quantification to the Sub‐Picomolar Range

open access: yesSmall Methods, EarlyView.
Single‐molecule fluorescence detection can become highly challenging for diluted concentrations in the picomolar range. This “low concentration barrier” is broken into and achieves quantitative detection down to 0.1 pM. Introducing a diaphragm into a standard confocal microscope and implementing fluorescence lifetime correlation spectroscopy (FLCS ...

From Single to Multi‐Material 3D Printing of Glass‐Ceramics for Micro‐Optics

open access: yesSmall Methods, EarlyView.
This article explores advancements in two‐photon lithography (TPL) for fabricating high‐refractive‐index micro‐optics. It examines single and multi‐material 3D architectures in glass and ceramics (GLACEs), highlighting photoresin customization, critical fabrication conditions, and cross‐scale structural and optical characterization.
