Luminescent hybrid materials based on nanodiamonds

Luminescent hybrid materials based on nanodiamonds
Luminescent hybrid materials were prepared by covalently functionalizing nanodiamonds (NDs) with rare earth (RE) complexes. Pyromellitic acid (PMA), as the organic sensitizer, was grafted onto amino-terminated NDs to chelate lanthanide ions (Eu3+ and Tb3+). The emission colors of the hybrid composite of ND-PMA-Eu x Tb y can be tuned from red to orange, yellow and green by adjusting the molar ratio of Eu3+ to Tb3+. Moreover, the luminescence of the hybrid composites exhibits remarkable photostability under ultraviolet irradiation for 60 h. As a proof-of-concept experiment, the as-synthesized ND-PMA-Eu and ND-PMA-Tb were employed as the phosphors for red and green light-emitting-diode (LED) devices with ultraviolet (UV) chips. Therefore, the nanodiamond-based luminescent hybrid material may find potential application in optical device.
