  • Encapsulated quantum sized doped semiconductor particles and method of manufacturing same
    Patent number: 6048616
    Abstract: Doped encapsulated semiconductor nanoparticles of a size (<100 .ANG.) which exhibit quantum effects. The nanoparticles are precipitated and coated with a surfactant by precipitation in an organometallic reaction. The luminescence of the particles may be increased by a further UV curing step.
    Type: Grant
    Filed: October 4, 1994
    Date of Patent: April 11, 2000
    Assignee: Philips Electronics N.A. Corp.
