| The fluorescence responses of DMCS-TPA towards mechanical,thermal and solvent-fuming processes are illustrated in Fig. 4.The as-prepared powder switch from yellowish green (¦Ëem= 512 nm, ¦µf= 48.59%) to orange (¦Ëem= 599 nm, ¦µf= 3¦µ4.53%) luminescence was accompanied by the colour change from yellow to orange upon grinding. As shown in Fig. 5a, the PL spectra of the initial powder are significantly red-shifted by 87 nm with the peak width (FWHM) broadened from 69 nm to 116 nm after grinding. The remarkable conversion of the maximum PL wavelength is among the best results reported currently,which is enough clear to be readily visualized by the naked eye. |
