Abstract
Numerical calculation has been undertaken on the temperature dependence of photoluminescence (PL) intensity and PL lifetime offac tris(2-phenylpyridine) iridium (Ir(ppy)3) phosphorescent material doped in 4,4'-bis[N-(p-tolyl)-N-phenyl-amino] biphenyl (TPD) and compared with the experimental result. Good agreement is obtained between the observed and calculated PL intensities and lifetimes. Calculation is also made for the PL intensity and lifetime of the emission from the triplet state of TPD.
