 Spodumene (an aluminium and lithium silicate) phosphoresces very brilliantly with a rich golden yellow colour, but shows no spectrum line, only a strong concentration of light in the orange and yellow. A phosphorescing crystal of Spodumene has all the...  Proceedings of the Royal Society of London - Page 203by Royal Society (Great Britain) - 1881Full view - About this book
