Optical spectroscopy – Techniques, instrumentation, and typical molecular and nanoscale reporters
(2018)
Different types of optical spectroscopies are introduced with special emphasis on method-inherent limitations and reliable instrument calibration and performance validation. In addition, different classes of molecular and nanocrystalline emitters are presented and the underlying photophysical processes are briefly described.
Mandatory for the comparison of different emitter classes and the rational design of the next generation of molecular and nanoscale reporters are reliable and quantitative photoluminescence measurements. This is of special relevance for all fluorescence applications in the life and material sciences. In the following, procedures for the determination of this spectroscopic key parameter are presented including pitfalls and achievable uncertainties and material-specific effects related to certain emitter classes are addressed.
