The experimental data are analysed with the following conclusions. The molecular decay time τ0 of a thin anthracene crystal lamina at room temperature is 10 nsec. The thick crystal values are increased by self-absorption to 31.6 nsec (volume excitation, e.g. by γ-rays), 24.1 nsec (surface excitation, e.g. by ultra-violet or α-rays, and emission observed by transmission) and 19.4 nsec (surface excitation, and observation by reflection). Surface oxidation or reduction in crystal thickness yields… Expand
Variations in the Efficiency of Fluorescence Excitation in Anthracene
The efficiency with which fluorescence is excited in single crystals of anthracene has been reported to vary considerably with both the excitation wavelength and the condition of the crystal. TheseExpand

TLDR
The mapped EMD in a single crystal of anthracene by two-dimensional angular correlation of positron annihilation radiation (2D-ACAR) has exhibited evidence for the absence of free volume defects. Expand
