Nowadays, photoluminescence sensors offer a wide range of possibilities for chemical sensing. The optimal design of a chemical sensor based on photoluminescence involves the selection of a luminescent dye and immobilizing matrix (appropriate for the target analyte and the measuring conditions), optoelectronics transducers, measuring magnitudes (intensity or lifetime), and procedures (either in the time or frequency domain), taking into consideration the measuring range, required accuracy, and cost of the instrument. As in any measuring system, the analyte determination requires, in addition to the measurement of the luminescent response, a calibration of the sensor.
Calibration is one of the current challenges in photoluminescence sensors, because of the degradation of many dyes, the costs associated to calibration, or the deviation of the calibration curves from theoretical models for particular immobilizing matrices, for extreme ranges of the analyte concentration, or because of interfering processes.
The aim of this Special Issue is to reflect on the latest improvements in the calibration of photoluminescence sensors, encompassing the application of novel strategies in order to simplify the calibration, as well as to allow for the miniaturization and simplification of chemical devices.
The Special Issue is dedicated to presenting robust strategies and statistically sound analysis procedures so as to calibrate photoluminescence sensors, including the estimation of intensity, lifetime, ratio measurements, self-referenced strategies, estimation of sensitivity, error evaluation, and any other related aspect, which should rely on the integration between statistical strategies and real measurements. Studies based on the application of novel strategies of the calibration and measurements of real samples, including comparisons of standard methodologies, are welcome.
In this framework, we are glad to edit this Special Issue on “Calibration of Chemical Sensors Based on Photoluminescence". We invite manuscripts on all aspects pertinent to the calibration of photoluminescence optical sensors. Both reviews and original research articles are welcome.
If you have any suggestions that you would like to discuss beforehand, please feel free to contact us. We look forward to and welcome your participation in this Special Issue.
