主　　题：AIE microfiber deep-blue emission energy transfer optical waveguide white light emission 

摘      要：The development of high-performance organic blue light-emitting emitters is in urgent to act as an excitation source to contribute the white light *** the other hand,the investigation on optical waveguides have been received increasing attentions because they can manipulate the light propagation accurately in the microscale to boost the optoelectronic and energy conversion *** this work,we facilely prepared a deep-blue aggregation-induced emission(AIE)dye,namely TPP-4OMe,which shows high luminescent efficiency,narrow emission band and good stability in the aggregate ***-4OMe can be fabricated as deep-blue AIE microfibers readily with definite morphology and *** on the AIE microfibers,the active waveguide to transmit deep-blue emission signals can be achieved with a very low optical loss coefficient(α)of 6.7×10^(−3)dBμm^(−1).Meanwhile,the full-visible broadband low-loss passive waveguide can be well performed with these AIE microfibers,which has never been observed in the pure organic *** interestingly,the excellent properties of AIE microfibers enable them to act as a wave-guiding excitation source,resulting in a distinct and pure white light *** present work not only provides excellent blue light-emitting materials but also bridges the waveguide to realize the efficient white light emission to accelerate the practical applications.
