Excitation Wavelength-Dependent Nearly Pure White Light-Emitting Crystals from a Single Gold(I)-Containing Complex

A gold(I) complex is reported. Interestingly, crystals of the gold(I) complex exhibit an excellent excitation wavelength-dependent emission effect at room temperature. Notably, a nearly pure white emission with Commission Internationale de L’Eclairage (CIE) 1931 chromaticity coordinates of (0.32, 0.33) is obtained upon excitation with 406 nm light.
