Electrophotoluminescence in a Rigid 3-Methyl Pentane Solution of N,N,N’ , N’-Tetramethyl-p-Phenylenediamine at 77K
During studies to refine the model of the electrophotoluminescence phenomenon in photoionized solutions of N,N,N’,N’-Tetramethyl-p-phenylenediamine at 77K, a previously unreported contribution to the total recombination luminescence has been uncovered. Characteristics of the group of recombinations giving rise to this luminescence are described, and compared and contrasted with those of the recombinations which involve the biphotonically produced trapped electrons previously reported in this system. The results suggest that a compact charge-pair is responsible for the new luminescence.
The possibility that coupling of the applied electric field with the polarizable cation is responsible for the electrophotoluminescence found in this system is also discussed.
