Aromatic Difluoroboron β‑Diketonate Complexes: Effects of π‑Conjugation and Media on Optical Properties

, 2016
Aromatic difluoroboron β-diketonate complexes (BF2bdks) are classic fluorescent molecules that have been explored as photochemical reagents, two-photon dyes, and oxygen sensors. To gain a better understanding of their emissive properties in both solution

Recent Developments in Halide Perovskite Nanocrystals for Indirect X‐ray Detection

Advanced Materials Technologies, Volume 9, Issue 20, October 21, 2024.
Perovskite nanocrystals act as scintillators under X‐ray illumination with different conversion yield, stability, or decay times and outperform commercial materials, depending on their composition, host matrix, and luminescence process. Besides the lead halide perovskites, there are lead‐free alternatives providing self‐trapped exciton emission ...

Modulating Mechanochromic Luminescence Quenching of Alkylated Iodo Difluoroboron Dibenzoylmethane Materials

, 2016
Difluoroboron β-diketonate compounds exhibit solid-state luminescence phenomena. Among these are reversible mechanochromic luminescence (ML), aggregation induced emission (AIE), and mechanochromic luminescence quenching (MLQ).
