A water-soluble light-responsive antitumor agent, PtEuL, based on a cisplatin-linked europium-cyclen complex has been synthesized and evaluated for controlled cisplatin release by linear/two-photon excitation in vitro with concomitant turn-on and long-lived europium emission as a responsive traceable signal.

The influence of Eu concentration on the crystal structure and photoluminescence (PL) properties of Ca(PO):xEu (0.06 ≤ x ≤ 0.10) phosphors is systematically investigated using X-ray diffraction (XRD) Rietveld refinement, scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, UV-visible spectroscopy, and PL spectroscopy.

Developing sensitive and reliable methods for detecting antibiotics in water solutions is essential for protecting public health and the environment. Here, we report a novel fluorescent film with superior mechanical properties and detection response to ciprofloxacin (CIP), achieved through the in-situ growth of europium-based metal-organic frameworks on TEMPO-oxidized cellulose nanofibrils (TOCNF). Firstly, Eu(III) and 2,6-pyridinedicarboxylic acid (DPA) served as precursors, and a simple self-assembly strategy was employed to grow the composite film material (Eu-DPA@TOCNF) in situ on TOCNF, which exhibited characteristic emission peaks.

Using the solid-state reaction technique, varied YSiO phosphors activated by europium (Eu) ions at varied concentrations were made at calcination temperatures of 1000 °C and 1250 °C during sintering in an air environment. The XRD technique identified the monoclinic structure, and the FTIR technique was used to analyze the generated phosphors. Photoluminescence emission and excitation patterns were measured using varying concentrations of Eu ions.

As a novel fluorescent carbon nanomaterial, carbon dots are restricted by their poor fluorescence in the solid state, although they exhibit favorable photoluminescence in solution. N-doped carbon dots (N-CDs) and solid-state fluorescence films were prepared using green and renewable cellulose-derived materials, respectively. The hydrogen bonding network of carboxymethyl cellulose (CMC) inhibits the self-aggregation behavior of N-CDs, which leads to solid-state fluorescence.

Tetracyclines (TCs) residues pose a significant threat to the aquatic environment and human health, therefore this study aims to develop a simple, rapid, and sensitive TCs detection method. Herein, a dual-responsive gel probe (LDH-CES@N) was designed, consisting of the intercalation of graphene quantum dots into europium-doped layered double hydroxide (LDH). In the presence of TCs, the as-prepared probe exhibited dual emission fluorescence at 504 nm and 616 nm due to the synergistic effect of aggregation-induced emission and antenna effect.
