The invention of lasers, which took place a few decades ago, marks a milestone in the past, present, and future technologies in optoelectronics. In particular, the colorful and white tones produced by lasers are appealing from a utilization standpoint and align well with human eye perception. In this paper, an idea for a white laser based on the attractive perylene family of luminescent dyes is introduced. This concept provides multicolor emission and brilliant photostability upon external optical pumping. The main advantage of the approach is the construction of a fully organic and two‐component white laser. The versatility of the system is demonstrated by assembling multicolor, tunable, and efficient fluorescent systems using a liquid crystalline matrix, which is supported by comprehensive experimental studies. Additionally, by utilizing laser spectroscopy techniques, it is able to narrow the emission bandwidth and enhance the light in a typical synthetic polymeric matrix. This leads to the realization of white lasing emission with just two luminescent dyes: perylene blue and perylene orange.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
