Iridescence and Luminescence from Opal Matrices for Show Business

Н. В. Гапоненко, Svetlana M. Kleshcheva, Ekaterina I. Lashkovskaya, U. A. Zaitsau et autres

The paper reports on obtaining visually appealing images from opal matrices to artificial samples comprising regular packing of monodisperse silica globules. We show the images of iridescence, photoluminescence, and both of them simultaneously, exciting upconversion luminescence of Er3+ ions from BaTiO3 xerogel/opal …
