In order to investigate the effects of three coupling agents(MAPE, YB-510, KH-560) on the luminescence property, the mechanical property and the thermal stability of the rare earth fluorescent bamboo plastic composites, the fluorescence spectrophotometer, the electronic universal testing machine, the pendulum impact tester and the thermogravimetric analyzer are employed, in addition, the tensile fracture microstructures of the rare earth fluorescent bamboo plastic composites are observed by the field emission scanning electron microscopy(FESEM). The results show that the three coupling agents can improve the dispersion, the fluidity, the luminescence property, the bending strength, the bending modulus, the tensile strength and the impact strength of the rare earth fluorescent bamboo plastic composites. The scanning electron microscopy shows that the dispersibility and the interface bonding of the strontium aluminate phosphor are improved in the composites by using the coupling agent, the birdnesting is decreased too. The MAPE is better in improving the properties of the rare earth fluorescent bamboo plastic composites than the YB-510 and the KH-560. The thermogravimetric(TG) and derivative thermogravimetric(DTG) curves of the rare earth fluorescent bamboo plastic composites indicate that the KH-560 is better to improve the thermal stability of the rare earth fluorescent bamboo plastic composites, the YB-510 has an adverse effect on the thermal stability of the composites, and the MAPE has no effect on the thermal stability of the composites.
