The SiO2@SiO2:Tb(1,2‐BDC)3phen microspheres with monodispersed core‐shell structure, are kind of fluorescent particles, which are prepared by a seeded growth method under the catalysis of glacial acetic acid (1,2‐BDC, 1,2‐benzenedicarboxylic acid; phen, 1,10‐phenanthroline). Firstly, silica seed was fabricated by the hydrolysis of ethyl orthosilicate, and the Tb(1,2‐BDC)3phen was prepared by using...
A range of 3-indolyl-4-indazolyl maleimide fluorescent compounds, including 2a, 2b, 2c, 3a and 3b, were synthesized efficiently. In different organic dissolvents, the photo-physical performance was checked, either in the aggregated state or in the solid state. When being in solid and in solution state, these fluorescent compounds showed high fluorescent intensity, indicating a highest fluorescence...
This paper reports the photodegradation and recovery of two-photon fluorescence (TPF) in the chromophore AF455 doped in poly(methyl methacrylate) (PMMA) polymer, known to have a large two-photon absorption cross-section and a promising optical material for many applications. The self-healing of amplified spontaneous emission (ASE) in the DO11 system is also analysed.
