Time-resolved X-ray excited optical luminescence from tris(2-phenyl pyridine)iridium [corrected].
Time-resolved X-ray Excited Optical Luminescence (TRXEOL) has been developed to investigate the optical properties of a green organometallic phosphor, tris(2-phenyl pyridine)iridium, Ir(ppy)3. Using time-gated measurements, we find that the characteristic luminescence band from a neat Ir(ppy)3 film is composed of a fast channel at approximately 534 nm and a slower channel at approximately 580 nm. The implication of this study and the applicability of the technique in the study of light emitting materials are noted.
