The antibiotic type organic structure pefloxacin binds well with europium (III) ions as a useful scaffold for assembling optical probes and allows energy transfer from ligand to metal ions through coordination linkages. This water‐soluble chemosensor demonstrated significant ‘off–on (red)’ changes from an alkaline to a neutral environment (pH 14–8). The emission changed from red to blue under acidic...
Based on lanthanide optical materials, flexible and transparent luminescent films have been fabricated based on self-cracking micro-pattern on polydimethylsiloxane (PDMS) substrates. The morphology and photoluminescence were studied based on the self-assembly structures. The corresponding intra-molecular energy transfer and photophysical properties were evaluated. Results demonstrated that both lanthanide...
