摘要：

Selective excitation of anthracene in mixed crystals (host, dibenzofuran or biphenyl) containing guest molecules of anthracene and naphthalene-d8 at –195° produces naphthalene phosphorescence. This result is interpreted as energy transfer from T2 of anthracene to the host triplet, followed by exciton diffusion to naphthalene traps. Escape efficiency of triplet excitation from anthracene to naphthalene-d8 traps in dibenzofuran is (1.1 ± 0.3) × 10-4. © 1969, American Chemical Society. All rights reserved.
