  • A Photoluminescence Study of Dy3+ Emissions in Zircon from Central Highlands of Vietnam.pdf.jpg

  • It has been known that among REEs, Dy3+ plays an important role in the structure of Zircon though it just exists as trace elements. The Dy3+ is structured in the zircon crystalline lattice and it has a good fluorescent response. From all significant roles of this ion, this paper focused on clarifying the luminescence of Dy3+ in Zircon from a mine in Central Highlands of Vietnam (Krong Nang, Dak Lak province) by Photoluminescence (PL) spectroscopy, Energy Dispersive spectrometer (EDS). The analytical results of EDS identified the presence of trace quantities of Dy3+in the bulk of zircon by the typical peaks. The PL spectra showed Dy3+ emissions at some characterized band positions with...

  • Zircon occurs in many colors including various shades of pink, red, purple, yellow, orange, brown as well as less common shades of green, and blue. Generally, the colors of zircon are caused by the trace element composition (transition metals, lanthanides, actinides and REEs) and radiation damage (radiation induced color centers) [1]. The color centers of zircon are complex and the details surrounding the color-inducing mechanisms are still debated. The authors collected some zircon samples from Krong Nang mining, Central Highlandss, using UV-Vis-NIR and FTIR techniques to determine the causes of their color. The UV-VIS-NIR absorption spectra of these samples show continuous increase ...
