Nanocrystals in Glass

Relying on the electrochemical properties of tin oxides, engineers at the Los Alamos National Laboratory and the University of Milano-Bicocca have created an ultra-violet light emitting diode by embedding tin dioxide nanocrystals in glass, with a coating of tin monoxdide. An electrical current then causes the UV producing reaction, which these engineers believe will be useful in making inexpensive lab-on-a-chip devices and for activating light sensitive drugs inside the body.     MORE
