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.
Claims14
A chemically doped precipitated particle of semiconductor material of less than 100 .ANG. in diameter encapsulated with a surfactant, the surfactant maintaining a quantum confinement of said particle and further providing a surface passivation of said particle, the dopant concentration of said particle being 0.5-1.0%.
A particle of semiconductor material of less than 100 .ANG. in diameter, said particle chemically doped having a dopant of 0.5-1.0% concentration therein and encapsulated with a surfactant, the surfactant maintaining a quantum confinement of said particle and further providing a surface passivation of said particle.
