Used as a luminescent dopant in organic light-emitting diodes (OLEDs) due to its strong red emission under UV excitation. Employed in the synthesis of hybrid materials for optical sensors and bioimaging, leveraging its sharp emission bands and long fluorescence lifetime. Also applied in research for developing phosphors in display technologies and as a catalyst in selective organic transformations. The hydrate form improves solubility in polar solvents, facilitating its use in solution-based processing techniques.
