Low-Threshold and Narrow Linewidth Diffusive Random Lasing in Rhodamine 6G Dye-Doped Polyurethane with Dispersed ZrO$_2$ Nanoparticles [PDF]
J. Opt. Soc. Am. B 31, 2363-2370, (2014), 2015 We report on low-threshold and narrow linewidth intensity feedback random lasing in Rhodamine 6G dye-doped polyurethane with dispersed ZrO$_2$ nanoparticles. Depending on the dye/particle concentration, the lasing threshold is (6.8--15.4) MW/cm$^2$ and the linewidth is (4--6) nm. The lasing threshold as a function of nanoparticle concentration is found

Lanthanide(III) complexes of rhodamine-DO3A conjugates as agents for dual-modal imaging [PDF]
, 2013 Two novel dual-modal MRI/optical probes based on a rhodamine-DO3A conjugate have been prepared. The bis aqua-Gd(III) complex Gd.L1 and mono aqua-Gd(III) complex Gd.L2 behave as dual-modal imaging probes (r1 = 8.5 and 3.8 mM-1s-1 for Gd.L1 and Gd.L2 ...

Synthesis, resolution and crystal structures of two enantiomeric rhodamine derivatives
Acta Crystallographica Section E: Crystallographic Communications, 2017 The title molecule, rac-6′-bromo-3′-diethylamino-3H-spiro[2-benzofuran-1,9′-xanthen]-3-one, C24H20BrNO3, was synthesized and the two enantiomers which formed were separated. The structures of all three compounds were determined and compared with those of

Results in Chemistry, 2023 Maslinic acid was converted via a di-acetylated piperazinyl amide into rhodamine conjugates differing in their alkyl moieties. These conjugates were submitted to cytotoxicity assays employing a panel of human tumor cell lines. These conjugates held high cytotoxicity but also some selectivity especially for A2780 cells.
