Georges Destriau

from Wikipedia, the free encyclopedia

Georges Destriau (born August 1, 1903 in Bordeaux , † January 20, 1960 in Paris ) was a French physicist and discoverer of electroluminescence .

Career and research work

In 1926 Destriau became an engineer at the École Centrale des Arts et Manufactures in Paris. He then worked in industry on X-ray machines . From 1932 to 1941 Destriau worked at the center national de la recherche scientifique . He then went to the University of Bordeaux and in 1943 to Paris . In 1946 Destriau became a professor at the University of Poitiers and in 1954 at the Sorbonne in Paris. Destriau later worked for Westinghouse Electric .

Destriau worked in the field of magnetism and X-ray dosimetry of ionizing radiation. Best known are his research on electroluminescence, which he carried out in 1935 in the Paris laboratory of Marie Curie , who had died two years earlier . Destriau observed that with traces of copper - ions "contaminated" ( doped ) zinc sulfide crystals, suspended in castor oil between two mica flakes , a strong alternating electric field upon application fluoresce . He later replaced the castor oil and mica with a polymeric binder. The effect of electroluminescence is therefore also referred to in some publications as the Destriau effect . According to some publications, Destriau was also the first to use the term electrophotoluminescence . He himself called the light Lossew- Licht in his publications , after the Russian high-frequency engineer Oleg Lossew , who observed a light effect (also electroluminescence) on silicon carbide crystals in 1927 . The effect was largely forgotten. It was only “discovered” again towards the end of the 1960s, and everyday products were created from the “laboratory phenomenon”.
