Barium platinocyanide
웹2024년 4월 1일 · On Friday, 8 November 1895, Wilhelm was reproducing earlier work using low-output Lenard tubes, whereby fluorescence was visible on a screen coated with barium platinocyanide. He moved on to a higher output Hittorf-Crookes tube and reproduced the same phenomenon on a screen located near the tube.
