Patent ID: 7569984

Claim:
A white-light fluorescent lamp having silicon quantum dots, comprising: a luminescence generating device, said luminescence generating device comprising a first conductive substrate; a luminescence layer having silicon quantum dots; and a metal film, wherein said luminescence layer having silicon quantum dots both overlies and directly contacts an upper surface of said metal film; an electron emitting device, said electron emitting device comprising a second conductive substrate and a carbon nanotube layer; at least one separating plate, said separating plate being located between said luminescence generating device and said electron emitting device to obtain a vacuum between said luminescence generating device and said electron emitting device; and a high-voltage circuit, said high-voltage circuit comprising at least one high-voltage source, an anode end of said high-voltage circuit connecting to said first conductive substrate, a cathode end of said high-voltage circuit connecting to said second conductive substrate.
