Mineral fluorite or fluorspar (CaF2) can host significant quantities of trivalent REE3+ (rare earth element) by substitution with divalent Ca2+. The fluorites associated with carbonatites are often REE-rich compared to those derived from sedimentary, hydrothermal, or Mississippi Valley-type (MVT) fluorites. The naturally occurring fluorites have several industrial applications one of which is for luminescence. Whether or not REE enriched, the fluorite makes an ideal host for REEs, which are very important phosphors. The naturally occurring fluorites are available in sufficient quantities to cater to the industrial demand. Investigations have been carried out on the fluorites from active fluorite mines at Dongargaon in central India. Thermoluminescence behavior of a natural fluorite sample was investigated using a Nucleonix TL 1009I thermoluminescence reader. Multiple traps formed in the broad thermoluminescent (TL) glow curve were found by TL anal deconvolution software. Trapping parameters for all multiple traps formed on deconvoluting broad TL glow curve were found by different methods like Initial rise method, Chen's Peak shape method and Ilich method.

印度 Dogargaon 萤石矿天然萤石样品的热释光特性定制和捕集参数评估
通过用二价 Ca 2+取代，矿物萤石或萤石 (CaF 2 ) 可以容纳大量的三价 REE 3+（稀土元素）. 与来自沉积、热液或密西西比河谷型 (MVT) 萤石的萤石相比，与碳酸岩伴生的萤石通常富含稀土元素。天然萤石有多种工业应用，其中之一是用于发光。无论是否富含 REE，萤石都是 REE 的理想宿主，REE 是非常重要的磷光体。天然萤石的数量足以满足工业需求。已经对印度中部 Dongargaon 的活跃萤石矿中的萤石进行了调查。使用 Nucleonix TL 1009I 热释光读数器研究天然萤石样品的热释光行为。TL anal deconvolution 软件发现了在宽热释光 (TL) 辉光曲线中形成的多个陷阱。
