Integrating highly efficient luminescent dyes into poly(methyl methacrylate) matrices with well-defined parameters, such as degree of polymerization and dispersity, is a key step in the development of emerging technologies such as fiber-based solar collectors, sensors, contactless coupling devices and integrated light sources. In this work, four perylene-based fluorescent dyes, perylene from Sigma-Aldrich, Lumogen F Yellow 083 from BASF, Perylene Orange from TCI and Lumogen F Red 300 from BASF, were polymerized in bulk with methyl methacrylate. The molecular weight distribution was controlled by the ratio between the chain transfer agent and initiator and was measured by size exclusion chromatography. A dopant-dependent increase in the degree of polymerization, in which the dye causes a drop in the concentration of active growing polymer chains, was observed. Spectroscopic online monitoring of the process in transmission mode confirmed this observation and indicated the formation of stable perylene radicals during the polymerization. Comparative experiments with fluorescent (metal) organic dyes did not show a similar effect. Fitting models for the dye-dependent molecular weights for Lumogen Yellow and Lumogen Red are proposed.

Polymer optical fibres are increasingly being used for medical applications, e.g. as wearable devices for diagnostics or therapeutics. Due to the multitude of applications and the corresponding restrictions and prerequisites, the properties of these optical fibres are fine-tuned to their specific application. Regarding wearables and continuous, unobtrusive long-term monitoring, a very low burden is reached when the integration into textiles is complete and the wearer's comfort is ensured. Here, we discuss a selection of recent solutions within wearable photonic sensors. Integration processes are highlighted so as to provide insight for further development. Finally, implications of long-term monitoring are discussed including data mining. The effect of knowing one's vitals on society is highlighted as a relevant influence on medical care. If ubiquitous monitoring were realized for a high percentage of the population, concerns can arise regarding the long-term reliability of photonic sensors as well as ethical use of patient data.

“…This length was chosen due to practical reasons. In general, the length of the fiber should only influence the sensor performance in extreme cases for short and long fibers, as the fluorescence emission tends to saturate in the absence of stimulated emission after a short fiber length [ 18 ]. The coupling efficiency from the pump light delivery fiber to the POF was roughly 85%.…”

In recent years, lanthanide-doped nanothermometers have been mainly used in thin films or dispersed in organic solvents. However, both approaches have disadvantages such as the short interaction lengths of the active material with the pump beam or complicated handling, which can directly affect the achievable temperature resolution. We investigated the usability of a polymer fiber doped with upconversion nanocrystals as a thermometer. The fiber was excited with a wavelength stabilized diode laser at a wavelength of 976 nm. Emission spectra were recorded in a temperature range from 10 to 35 ∘C and the thermal emission changes were measured. Additionally, the pump power was varied to study the effect of self-induced heating on the thermometer specifications. Our fiber sensor shows a maximal thermal sensitivity of 1.45%/K and the minimal thermal resolution is below 20 mK. These results demonstrate that polymer fibers doped with nanocrystals constitute an attractive alternative to conventional fluorescence thermometers, as they add a long pump interaction length while also being insensitive to strong electrical fields or inert to bio-chemical environments.
