Tunable fluorescence emission from blue to red (see Figure) is exhibited by nanoparticles of 1,3,5‐triphenyl‐2‐pyrazoline (TPP) doped with 4‐(dicyanomethylene)‐2‐methyl‐6‐( p ‐dimethyl‐aminostyryl)‐4H‐pyran (DCM); the emission is found to be dependent on the amount of DCM dopant used. Efficient energy transfer is also shown to occur between TPP and DCM molecules.
