pHantastic Fluorescence of Narra Wood. Two articles by Mark Muyskens, "The Fluorescence of Lignum nephriticum: A Flash Back to the Past and a Simple Demonstration of Natural Substance Fluorescence and the JCE Classroom Activity "pHantastic Fluorescence", explore the fluorescence from the aqueous extract from shavings of the tropical hardwood narra. The fluorescence is dramatically pH dependent and can be turned on and off repeatedly using commonly available acid and base solutions. The cover shows a beaker viewed from above containing a solution made from one narra wood shaving. The left side of the beaker shows the blue fluorescence of the solution excited by a 400-nm UV LED. The right side is over a white surface to show the yellow appearance of the solution and the narra shaving.
