摘要

摘要采用熔淬技术合成了掺杂不同含量Sm3+离子的磷酸铝钆钾(KAGP)。样品进一步用于测量一些物理、光学和发光性能。吸收光谱分别在402和1233 nm处出现6h52→6P3/2和6h52→6F7/2的超敏跃迁。在401 nm激发下记录了光致发光光谱，在562、597、644和703 nm处分别出现了4G5/2→6HJ (J = 5/ 2,7 / 2,9 / 2,11 /2)跃迁，Sm3+的浓度在1.0 mol%处猝灭。采用最高浓度的Sm3+作为发射光谱，采用Judd-Ofelt (J-O)分析方法计算了不同激发态下的跃迁概率(AR)、辐射寿命(τR)、分支比(βR)和受激发射截面(σ(λp))等辐射特性。从J-O参数的结果发现，Ω2 > Ω6 > Ω4，辐射性能的最大值为4G5/2→6H7/2跃迁。低浓度的衰减曲线为单指数曲线，高浓度的衰减曲线为非指数曲线。根据色度坐标(Commission Internationale de l’eclairage)，表明掺Sm3+离子1.0 mol%的KAGP玻璃位于橘色区。掺杂浓度为1.0 mol%的Sm3+的KAGP玻璃在开发橙色激光器方面具有潜在的应用前景，也适用于光学器件。关键词:光谱;物理性质;磷酸盐;Kaewkhao感谢泰国科学研究与创新(TSRI)对这项研究的部分支持。披露声明作者未报告潜在的利益冲突。本研究项目由泰国国家研究委员会(NRCT)在皇家金禧(RGJ)博士项目下资助(合同编号:N41A640227)。

Luminescence Behavior of Sm ³⁺ Ion Doped Potassium Aluminium Gadolinium Phosphate Glasses as Orange Laser and Photonics Applications

AbstractPotassium aluminium gadolinium phosphate (KAGP) doped with difference contents of Sm3+ ion were synthesized by melt-quenching technique. The samples were further used to measure some physical, optical and luminescence properties. Absorption spectra show the hypersensitive transitions 6H5/2 → 6P3/2 and 6H5/2 → 6F7/2 at the wavelengths 402 and 1233 nm respectively. The photoluminescence spectra were recorded under 401 nm excitation, displayed the emission bands at 562, 597, 644 and 703 nm that corresponding to the transitions 4G5/2 → 6HJ (J = 5/2, 7/2, 9/2, 11/2) respectively, and the concentration quenching of Sm3+ showed at 1.0 mol%. Using the highest concentration of Sm3+ for emission spectra, Judd–Ofelt (J–O) analysis was performed to calculate the various radiative properties such as transition probabilities (AR), radiative lifetimes (τR), branching ratios (βR) and stimulated emission cross-section (σ(λp)) for different excited states. From the results of J–O parameter found to be Ω2 > Ω6 > Ω4 and the highest value of radiative properties was 4G5/2 → 6H7/2 transition. The decay curve for lower concentration was single exponential and became non-exponential for higher concentrations of the 4G5/2 level.

The KAGP glass doped concentration of Sm3+ at 1.0 mol% has potential application in developing the orange laser and suitable for optical device also.Keywords: Spectroscopicphysical propertiesphosphatesamariumglass AcknowledgmentJ.

期刊介绍： Integrated Ferroelectrics provides an international, interdisciplinary forum for electronic engineers and physicists as well as process and systems engineers, ceramicists, and chemists who are involved in research, design, development, manufacturing and utilization of integrated ferroelectric devices. Such devices unite ferroelectric films and semiconductor integrated circuit chips. The result is a new family of electronic devices, which combine the unique nonvolatile memory, pyroelectric, piezoelectric, photorefractive, radiation-hard, acoustic and/or dielectric properties of ferroelectric materials with the dynamic memory, logic and/or amplification properties and miniaturization and low-cost advantages of semiconductor i.c. technology.
