Abstract
Multicolor emission exhibited by complex organic systems is interesting and desired phenomenon for many optical applications. Laser devices capable to emit the light in the spectral range of three fundamental colors (red, green and blue) can revolutionize the modern display and lighting technologies. In this paper we demonstrate a multicolor stimulated emission (STE) phenomenon obtained in dye doped, liquid crystalline (LC) material. The polychromatic STE was obtained for LC cell, filled with nematic mesophase doped with three luminescent dyes. The CIE XYZ chromaticity diagram (1931) demonstrates effective color modulation with respect to relative concentration of utilized dyes and applied voltage. The precise color adjustment can be provided by applying the external electric DC fields, with voltages ranging from 0 to 20 V.
