The series of Mn²⁺ single doped fluoride-based K₃Ca₂(SO₄)₃F phosphor was prepared by the conventional high temperature solid-state reaction method. The formation of phase purity and morphology was studied by the XRD and SEM analyses. The prepared material was irradiated by γ-rays from ⁶⁰Co source and the thermoluminescence (TL) characteristic was carried out by Nucleonix 1009I TL reader. The prominent TL dosimetry peak observed for K₃Ca₂(SO₄)₃F:1mol% Mn²⁺_, annealed at 800°C centred at 217°C, revealed deeper traps. The TL exhibits a linear response as a function of dose rate up to 4 kGy. The computerised glow curve deconvolution (GCD) method, employed for the analysis of TL glow curve, shows the kinetics of the first order. The trapping parameters were evaluated using Chen’s peak shape method, initial rise method and Ilich method. The results exhibit that the synthesised phosphor was found to be a potential candidate for radiation dosimetry applications.

采用常规高温固相反应法制备了Mn ²⁺单掺杂氟化物基K ₃ Ca ₂ (SO ₄ ) ₃ F系列荧光粉。通过XRD和SEM分析研究相纯度和形态的形成。制备的材料用⁶⁰ Co 源的 γ 射线辐照，并通过 Nucleonix 1009I TL 阅读器进行热释光 (TL) 特性分析。K ₃ Ca ₂ (SO ₄ ) ₃ F:1mol% Mn ²⁺观察到的显着 TL 剂量测定峰_，以 217°C 为中心在 800°C 下退火，揭示了更深的陷阱。TL 表现出线性响应，作为高达 4 kGy 的剂量率的函数。用于分析 TL 辉光曲线的计算机化辉光曲线解卷积 (GCD) 方法显示了一级动力学。使用陈氏峰形法、初始上升法和 Ilich 法评估捕获参数。结果表明，合成的磷光体被发现是辐射剂量测定应用的潜在候选者。
