Little and Parks demonstrated that the superconducting transition temperature ${T}_{c}$ of a multiply connected superconductor is periodic in a magnetic field with a periodicity of $\frac{\mathrm{hc}}{2e}$. However, there were certain anomalous featu

We have observed delayed fluorescence in tetracene crystals excited by near infrared light. Measurements on both prompt and delayed fluorescence were carried out between room temperature and -82 °C. The dependence of the delayed fluorescence intensi

The component of the triplet-exciton diffusion along the crystal $a$ axis was measured in anthracene crystals at 118, 160, 298, and 371 \ifmmode^\circ\else\textdegree\fi{}K, and found to be ${D}_{\mathrm{aa}}=(4.0\ifmmode\pm\else\textpm\fi{}0.5),(2.5

Magnetic-field modulation of delayed fluorescence from poly(2-vinylnaphthalen) in a low-temperature glass at 77 K is reported. The observations are interpreted in terms of local ordering of the naphthalene chromophores with their normal axes aligned

Triplet exciton fusion and singlet excition fission have been observed in tetracene crystals, and the magnetic field dependence and the rate constants for these processes have been measured. At 0\ifmmode^\circ\else\textdegree\fi{}C the singlet fissio
