Used as a luminescent dopant in organic light-emitting diodes (OLEDs) due to its strong red emission under UV excitation. It is also employed in sensing applications, particularly in oxygen and temperature sensors, where its phosphorescence properties allow for precise optical detection. Additionally, it serves as a shift reagent in NMR spectroscopy, helping to resolve complex spectral signals in fluorinated compounds. Its thermal stability makes it suitable for use in vapor-deposited thin films for optoelectronic devices.
