Optical enhancement with nanoparticles and microcavities

A method of enhancing the optical emission of a material comprising the steps of:

• a) doping a medium, the medium comprising a plurality of nanoparticles selected from the group consisting of non-aggregated nanoparticles, and aggregated nanoparticles comprising fractals, with the material;
• b) exciting the doped medium with at least one light source;
• and
• c) locating the doped medium in the vicinity of a microcavity.

An amplifying apparatus having a gain greater than 1.2, said apparatus comprising:

• at least one light source;
• a microcavity;
• and
• a medium, said medium comprising a plurality of nanoparticles selected from the group consisting of non-aggregated nanoparticles, and aggregated nanoparticles comprising fractals, said medium located in the vicinity of said microcavity to enhance optical emission.

A method of amplification comprising the steps of:

• a) providing a medium comprising a plurality of nanoparticles selected from the group consisting of non-aggregated nanoparticles, and aggregated nanoparticles comprising fractals;
• b) locating the medium in the vicinity of a microcavity to amplify optical emission;
• and
• c) exciting the medium with at least one light source.
