In this work we will present our concept of direct fluorescence analysis using Ge- or rare earth-implanted Si based light emitters for the detection of estrogen in waterish solutions. We will discuss the performance of these light emitters in terms of efficiency, operation lifetime, stability, and operation voltage and show that they are generally suitable for lab-on-chip applications. In addition we report about the composition and fabrication of a bioactive layer on top of the light emitters which has the task to immobilize estrogen selectively from a waterish sample. Finally, the interaction of a Tb-implanted light emitter with a quantum dot dye is investigated.
