Exploration of structural and luminescent properties of Tb3+-doped Ca12Al14O33 phosphors: potential for plasma display panel technology
This study examines the impact of doping Tb3⁺ ions into Ca12Al14O33 to analyze its structural and luminescent properties for potential use in plasma display panels (PDPs). Phosphors were synthesized via the sol–gel method and characterized using XRD, FT-IR, SEM, and PL techniques. Morphological observations via SEM revealed micron-sized, irregularly shaped particles, outlining the distinct morphology of the material. Luminescence investigations revealed an improved energy transfer process apparent in the emission and excitation spectra. Under ultraviolet (UV) and vacuum ultraviolet (VUV) excitation, the predominant green emission at 543 nm, attributed to the 5D4 → 7F5 transition of Tb3+ ions, exhibited optimal luminescent properties up to a Tb3+ concentration of 0.07 mol. However, the subsequent decrease in emission intensity beyond this threshold occurred due to a concentration-quenching effect. Further analyses demonstrated vacuum photoluminescence at 147 nm and 172 nm, exhibiting robust green emissions at 543 nm associated with the 5D3, 5D4 → 7FJ transitions inherent to Tb3+ ions. Moreover, all samples exhibited color purity ranging from 85 to 95%. The exceptional luminescence attributes of Ca12Al14O33:Tb3+ signify its potential in diverse applications. Notably, its promising applicability in PDP stems is due to its specific emission peaks and luminescent behavior. This study presents avenues for future research, emphasizing potential optimization strategies for PDP applications and exploring the properties of phosphors across various technological domains.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
