Although multiple emissive phosphors are of great fundamental interest and practical importance, it is still challenging to achieve full-color tunable luminescence in a single-component material. Herein, we present an antimony-doped lead halide single crystal (C10NH22)2PbBr4: Sb3+ with widely tunable red/green/blue/white luminescence. Extrinsic Sb3+ dopants provide host another active sites to capture photo-generated excitons, thus triggering blue/red dual emission. Moreover, a reversible thermal-induced phase transition transforms blue/red emission into green/red dual emission. Both two phases exhibit intriguing excitation-wavelength dependent emission, affording a whole color gamut covering the red-green-blue (RGB) color triangle on the CIE 1931 diagram. Exptl. and theor. calculation studies reveal two emitters work independently, which paves the way for the multimode optical control and promotes the development of multifunctional luminescent materials. In the experiment, the researchers used many compounds, for example, 1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6COA of Formula: C10H16BrN).
1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.COA of Formula: C10H16BrN
