METHOD AND DISCHARGE LAMP FOR PRODUCING OPTICAL RADIATION Russian patent published in 1997 - IPC

FIELD: generation of optical radiation by electrical discharge in gas or in low-pressure lighting discharge lamps of various types. SUBSTANCE: method involves creation of gaseous discharge in inert gas atmosphere with radiating dope in bulb made of optically transparent material. Radiating dope is fullerene introduced at temperature of 300-800 C. Fullerene may be introduced in the form of fullerene-containing soot in concentration of at least 1.0 mass percent. It may be also introduced in the form of $$$. Discharge lamp implementing this method has bulb made of optically transparent material and filled with inert gas and radiating dope; used as the latter is fullerene in the amount of $$$ mcmol/cu.cm. Radiating dope may be introduced in bulb pip. EFFECT: facilitated procedure. 7 cl, 12 dwg
