Abstract Augmenting the photoluminescence (PL) properties of Samarium (Sm3+) doped Zinc Strontium fluoro-borosilicate glass (ZSFBSi glass) by varying the Sm3+ ions concentration unlocks new prospects for their application as luminescent devices. This paper presents absorption, photoluminescence (PL), energy transfer and color chromaticity parameterization of ZSFBSi glass doped with Sm3+ ions concentrations. The Judd-Ofelt (J-O) theory in correlation with absorption as well as PL spectra leads to the estimation of radiative parameters of the excited luminescent states of Sm3+ ions needed to understand the luminescent potentiality of the as-prepared glasses. The absorption spectral data reveals the nature of bonding between Sm3+ ions and oxygen ligands in the as-quenched glasses as ionic and the result is consistent with the J-O analysis. The PL spectra of as-quenched glasses exhibit greenish-yellow, orange-red, light red and red color ascribed to 4G5/2 → 6H5/2, 6H7/2, 6H9/2, 6H11/2 emission bands at 563, 599, 646 and 706 nm, respectively. The PL intensity enhances with an escalation in Sm3+ ions content until 1.0 mol% and reduces thereafter, owing to a proficient energy transfer (ET) process. The Dexter theory and Inokuti-Hirayama (I–H) model identified the foremost ET process associated with the as-quenched glasses as dipole-dipole in nature. The CIE color coordinates (x, y) and Correlated Color Temperature (CCT) were calculated to cognize the effectiveness of as-quenched glasses in radiative cool white emission. The estimated branching ratios, emission cross-sections, gain bandwidth, quantum efficiency, optical gain, color coordinates and CCT finally reveals that the as-quenched glasses can be used in luminescent devices and amide all, 1.0 mol% Sm2O3 in ZSFBSi glass is highly appropriate for white LEDs as well as orange-red luminescent devices.

Judd-Ofelt 分项和能量转移对 Sm3+ 离子活化的 B2O3-ZnF2-SrO-SiO2 玻璃的影响，用于橙红色发光器件

摘要 通过改变 Sm3+ 离子浓度来增强钐 (Sm3+) 掺杂的锌锶氟硼硅玻璃 (ZSFBSi 玻璃) 的光致发光 (PL) 特性，为其作为发光器件的应用开辟了新的前景。本文介绍了掺杂 Sm3+ 离子浓度的 ZSFBSi 玻璃的吸收、光致发光 (PL)、能量转移和色度参数化。与吸收和 PL 光谱相关的 Judd-Ofelt (JO) 理论导致对 Sm3+ 离子激发发光状态的辐射参数的估计，以了解所制备玻璃的发光潜力。吸收光谱数据揭示了淬火态玻璃中 Sm3+ 离子和氧配体之间的键合性质，结果与 JO 分析一致。淬火玻璃的 PL 光谱呈现黄绿色、橙红色、浅红色和红色，归因于 4G5/2 → 6H5/2、6H7/2、6H9/2、6H11/2 在 563、599、分别为 646 和 706 nm。由于熟练的能量转移 (ET) 过程，PL 强度随着 Sm3+ 离子含量的增加而增强，直到 1.0 mol%，然后降低。Dexter 理论和 Inokuti-Hirayama (I-H) 模型将与淬火玻璃相关的最重要的 ET 过程确定为自然界中的偶极-偶极。计算 CIE 颜色坐标 (x, y) 和相关色温 (CCT) 以了解淬火玻璃在辐射冷白光发射中的有效性。估计的分支比、发射截面、增益带宽、量子效率、光学增益、
