    Exploring the Photoluminescence Origins of Natural Boron Mineral (Tincal) and Its Waste Byproducts
    (SSRN 4891422, 2024-07-10) Karacaoglu, Erkul; Yungevis, Hasan; Acikgoz, Sabriye; Gul, Mert; Ates, Esen Gul; Yildirim, Cennet
    Many natural minerals can exhibit luminescence due to impurities and their crystal structures. Evaluating the waste generated from processing these materials presents significant research opportunities. This study explores tincal, a natural boron source, and its waste, discussing their structural and luminescence properties. Both the mineral and its waste show similar phases like dolomite and calcite. In terms of luminescence, both exhibit PL emission in the 500-650 nm range. Emphasis is placed on evaluating the waste, with heat treatment revealing notable changes. At temperatures exceeding 500°C, the waste transforms from dolomite to monticellite, causing a red-shift in PL emission to the 600-850 nm range. XPS analysis of untreated and heat-treated waste confirms elemental compositions, highlighting the influence of boron on structural changes during heat treatment, despite trace elements like Mn and Fe being undetected.
