  12. We can cheat „classical” optics

  13. “Labors of the Months” (Norwich, England, ca. 1480).(the rubycolour is probablyduetogoldnanoparticles mixed intotheglas.)

  14. The Lycurgus Cup (glass; British Museum; 4thCentury A. D.) When illuminated from outside, it appears green. However, when illuminated from within the cup, it glows red. Red color is due to very small amounts of gold powder (about 40 parts per million) in glass.

  15. Nanotechnology and colours Bulk Gold mp = 1064° C Color = gold 1 nm gold particles mp = 700 °C max = 420 nm Color = brown-yellow 20 nm gold particles mp = ~1000 °C max = 521 nm Color = red 100 nm gold particles mp = ~1000 °C max = 575 nm Color = purple-pink
