In the last few years, the sources of directional, coherent, and powerful White Light Emission (WLE) have been extensively studied due to their many possible applications in optoelectronics, imaging, and lighting. Future directions for research include the development of the WLE sources for the novel concept of fully wireless technology of data transmission entitled Light Fidelity (Li-Fi). The combination of different color-emitting laser dyes, together with compatible materials with targeted optical properties, can lead to the construction of different white lasers (WL), which is still a very novel topic. In the last few years, since the discovery of the first WL (2015), a rapid evolution of scientific interest from the topic of white fluorescence to white lasing has been noticed.
The aim of this work is to present these advanced devices, fabricated using organic dyes, liquid-crystalline systems, or a multifunctional phase-separated polymer matrix containing liquid crystals, ionic liquids, and multiple organic chromophores. Precise color tuning can be achieved by applying external DC electric fields or by increasing the delivered energy density (e.g., via higher-intensity optical or electrical pumping) [1-4] .
