| 简介 |
Group IV semiconductor nanocrystal doped with rare earths or other light emitting metal to form alternating current solid-state devices that can be designed to operate at a variety of voltages including line voltages. The semiconductor nanocrystals are preferably silicon, silicon carbide, germanium or germanium carbide, and the electric luminescent device may have an upper and lower thin coat of a semiconductor nanocrystal glass material in turn connected to alternating current electrodes. The present invention enables one to fabricate a solid-state light that can use standard fixtures, e.g. Edison type, and standard AC voltages and frequencies for use in houses and businesses without refurbishing the installed lighting fixtures. |
