CONTROL Emission spectrum of solid napthalene
without the mercury trimer. Emission is due to
monomer fluorescence.

• Science here has two important technological
  implications on the EL device industry

• Phosphorescence enhancement (100)
• Unlike naphthalene, solid pyrene gives excimer
  not monomer emission. Excimer emissions are not
  desired for organic fluorophores in EL
  applications. Solid-state interaction of pyrene
  with Hg3 units (see X-ray data) prevents pyrene
  from association.
