Abstract
The functionalization of phosphors through co-dopant interactions represents an effective and encouraging avenue for enhancing their luminescent characteristics. Co-doping introduces additional dopant species into the host lattice, leading to intricate interactions that influence the material's luminescence behavior. The synergistic effects arising from co-dopant interactions result in tailored luminescent characteristics, including emission wavelength tuning and improved performance in diverse applications such as lighting, displays, biomedical imaging, temperature measurement, and thermal imaging. By elucidating the intricacies of co-dopant interactions, this research contributes to the rational design and optimization of functionalized phosphors for advanced technological applications. By carefully selecting and controlling the dopants, researchers can tailor the luminescent characteristics of phosphors to meet specific requirements, thereby unlocking their full potential. This presentation focuses primarily on possible advantages of using this approach in luminescence thermometry and thermal imaging.Co-activating phosphors facilitates the development of multifunctional materials with diverse, not only luminescent, properties. By carefully selecting dopant combinations, controlling their concentrations, and managing the technological parameters, precisely designed phosphors exhibiting multi-modal functionalities can be fabricated.In the presentation, we will show examples of the effective use of co-doping phosphors with selected lanthanide ions or a lanthanide and a d-element. An exemplary case is presented in Figure 1, where temperature-dependent luminescence spectra of a triply-activated strontium aluminate phosphor are presented together with the relative thermal sensitivities derived from decay times of the different emissions.The Polish National Science Centre (NCN) financed the research under OPUS grant #UMO2023/49/B/ST5/04265.
