Praseodymium (Pr³⁺) ions doped barium lithium calcium zinc fluoroborate (BLCZFB) glasses were prepared with the melt quenching technique, and their physical, optical, and shielding properties were estimated. Their amorphous nature was verified with X-ray diffraction (XRD) pattern. Each of their absorption spectra exhibited nine peaks in the visible and near infra-red (NIR) regions. The absorption bands of oscillator strength and Judd-Ofelt (J-O) parameters were used to evaluate their radiative parameters. Their predominant emission peak in their visible emission spectra was observed at 604 nm (16556 cm⁻¹), attributed to ¹D₂→³H₄ transition. And their main emission peak in the NIR emission spectra was at the wavelength of 1458 nm (6858 cm⁻¹), corresponding to the ¹D₂→¹G₄ transition. Their spectroscopic properties, including the stimulated emission cross-section (${\sigma }_P^E$), branching ratio (β_R), quantum efficiency (η), gain bandwidth (${\sigma }_P^E$$\times$Δλ_eff), and optical gain parameter (${\sigma }_P^E$$\times$τ_exp) were also calculated for the visible (¹D₂→³H₄) and NIR (¹D₂→¹G₄) emission transitions. From their emission spectra, the color chromaticity coordinates, (x, y) and (u, v), the color purity (CP), and the correlated color temperature (CCT) were calculated. The concentration quenching mechanism and energy transfer process were also explored from the emission spectra. Both the visible and the NIR lifetime curves exhibited non-exponential behaviour for all the glasses. The experimental lifetime decreases with the increase of Pr³⁺ ions concentration, which could be attributed to the cross-relaxation channels. The decay profiles are well fitted with Inokuti-Hirayama (IH) model (S = 6) to realize the energy transfer process. The energy transfer parameter (Q), donor-acceptor interaction parameter (C_DA), and critical distance (R₀) were also calculated. Next, the direct and indirect allowed transitions, the band tailing (B), and Urbach parameters (ΔE) were calculated. Then the shielding parameters, including the mass attenuation coefficient (MAC), the mean free path (MFP), and the equivalent atomic number (Z_eq), etc., were articulated. Based on the above parameters, 1PrBLCZFB and 2PrBLCZFB glasses are suggested to be used for future solid-state orange-red laser, photonic devices, optical amplifier, and gamma ray shielding.

采用熔融淬火技术制备了掺有（（Pr ³⁺）离子的氟硼酸钙锂锌硼玻璃（BLCZFB），并对其物理，光学和屏蔽性能进行了评估。用X射线衍射（XRD）图证实了它们的无定形性质。它们的每个吸收光谱在可见光和近红外（NIR）区域均显示9个峰。振荡器强度和Judd-Ofelt（JO）参数的吸收带用于评估其辐射参数。在604 nm（16556 cm ^-1）处观察到它们在可见光发射光谱中的主要发射峰，这归因于¹ D ₂ → ³ H ₄过渡。它们在NIR发射光谱中的主要发射峰位于1458 nm（6858 cm ^-1）的波长处，对应于¹ D ₂ → ¹ G ₄跃迁。它们的光谱特性，包括受激发射截面（${\sigma }_P^E$），分支比（β _{- [R} ），量子效率（η），增益带宽（${\sigma }_P^E$$\times$Δ λ _EFF）和光学增益参数（${\sigma }_P^E$$\times$τ _EXP）也计算用于可见（¹ d ₂ → ³ ħ ₄）和NIR（¹ d ₂ → ¹ ģ ₄）发射的转换。从它们的发射光谱中，色度坐标（（x，y）和（u，v），色纯度（CP）和相关色温（CCT））进行了计算。从发射光谱中探索了浓度猝灭机理和能量转移过程。对于所有眼镜，可见光和NIR寿命曲线都表现出非指数行为。随着Pr ³⁺离子浓度的增加，实验寿命降低，这可能归因于交叉松弛通道。衰减曲线与Inokuti-Hirayama（IH）模型（S  = 6）完全吻合，以实现能量传递过程。还计算了能量转移参数（Q），供体-受体相互作用参数（C _DA）和临界距离（R ₀）。接下来，直接和间接允许的过渡，带拖尾（B）和Urbach参数（ΔE）进行了计算。然后屏蔽参数，包括质量衰减系数（MAC），平均自由程（MFP），和等效原子序数（Ž_当量）等，分别铰接。根据上述参数，建议将1PrBLCZFB和2PrBLCZFB眼镜用于将来的固态橙红色激光器，光子器件，光放大器和伽马射线屏蔽。
