Investigation of characteristics of solid-state active media based on pyrromethene 567

Computational and Experimental Investigation of the Optical Properties of the Chromene Dyes

“…High reliability, stability and compactness of these devices lead to their potential usage in various fields of science, medicine, industry, communications, etc. During last years the number of active solid-state media were developed which emit light in a wide range of the electromagnetic spectrum. − It should be noted, that the most advanced lasers based on organic solid-state active media, for instance, coumarines, at present, emit in the blue-green region of the visible light spectrum. − In recent time a number of solid active media based on the BODIPY, − perylene, , rhodamine − dyes and dye-doped matrices with silica-containing polymers. , and hybrid matrices, , emitting in the orange and red regions have been successfully developed. − It is well-known that just the emission in the red range of the spectrum can deeply penetrate into biological tissues. Therefore, the creation of solid-state active medium emitting in this spectral range is a vital necessity in applied medicine.…”
