Abstract

Tm³⁺-doped zinc tellurite (TeBSrZnNaMg: Tm) and Ho³⁺-doped borophosphate (BPAgMgLiZn: Ho) glasses were synthesized via the melt-quenching technique. X-ray diffraction confirmed their amorphous nature. FTIR analysis identified characteristic functional groups. Optical absorption spectra revealed the ³H₆ → ³H₅ transition of Tm³⁺ at 1100–1250 nm, which is significant for infrared applications, while the ³H₆ → ³H₄ transition appeared at ∼800 nm. For Ho³⁺ ions, the 5I₈ → 5F₅ transition at 640 nm and 5I₈ → 5I₆ at 1150 nm were observed. The photoluminescence analysis showed emission peaks at 545 nm, 650 nm, and 750 nm for Ho³⁺, with CIE coordinates (x = 0.3215, y = 0.3246) and a CCT of 6057 K. TeBSrZnNaMg: Tm glass exhibited coordinates (x = 0.1684, y = 0.0075) and a CCT of 1916 K. The radiation shielding analysis showed that at 0.015 MeV, the linear attenuation coefficients were 155 cm⁻¹ (TeBSrZnNaMg: Tm) and 50 cm⁻¹ (BPAgMgLiZn: Ho), with MAC values of 38 and 13 cm²/g, respectively. The HVL was 4.77 cm and 8.173 cm, while TVL was 15 cm and 27.14 cm. FNRCS values were 0.082 cm⁻¹ and 0.138 cm⁻¹. The gamma-ray parameters such as Z_eff and mass attenuation coefficients of the fabricated glasses were studied with various energy ranges.

A high-purity germanium detector (ORTEC GEM 60P) with an energy resolution of 1.69 keV was used for gamma-ray measurements. JO parameters of both prepared glasses were studied. The results revealed that TeBSrZnNaMg: Tm and BPAgMgLiZn: Ho glasses are appropriate for blocking radiation.

用于辐射屏蔽应用的无铅掺杂 Tm3+ 离子碲锌玻璃和掺杂 Ho3+ 离子硼磷酸盐锌玻璃的合成、结构和光学特性

采用熔体淬火技术合成了Tm3+掺杂碲酸锌（TeBSrZnNaMg: Tm）和Ho3+掺杂硼磷酸盐（BPAgMgLiZn: Ho）玻璃。x射线衍射证实了它们的无定形性质。FTIR分析确定了特征官能团。光学吸收光谱显示Tm3+在1100 ~ 1250 nm处发生3H6→3H5跃迁，这对红外应用具有重要意义，而在~ 800 nm处出现3H6→3H4跃迁。对于Ho3+离子，在640 nm处发生5I8→5F5跃迁，在1150 nm处发生5I8→5I6跃迁。光致发光分析显示，Ho3+的发光峰分别位于545 nm、650 nm和750 nm处，CIE坐标（x = 0.3215, y = 0.3246）， CCT为6057 K。TeBSrZnNaMg: Tm玻璃的坐标为（x = 0.1684, y = 0.0075）， CCT为1916 K。辐射屏蔽分析表明，在0.015 MeV下，线性衰减系数为155 cm−1 （TeBSrZnNaMg: Tm）和50 cm−1 (bpagmglizzn: Ho)， MAC值分别为38和13 cm2/g。HVL分别为4.77 cm和8.173 cm， TVL分别为15 cm和27.14 cm。FNRCS值分别为0.082 cm−1和0.138 cm−1。在不同的能量范围内，研究了玻璃的射线参数Zeff和质量衰减系数。使用能量分辨率为1.69 keV的高纯度锗探测器（ORTEC GEM 60P）进行伽马射线测量。研究了两种玻璃的JO参数。结果表明，TeBSrZnNaMg: Tm和BPAgMgLiZn: Ho玻璃具有较好的阻挡辐射的性能。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
