Abstract Deep blue light-emitting diodes (LED) played a vital role in display devices and lighting. However, the emission wavelengths of blue light-emitting diodes reported at present were almost focused between 460—480 nm, while shorter emission have seldomly been reported. Citrate and urea based carbon dots system had many advantages in deep blue electroluminescent devices due to their tunable emissions through synthesis parameter adjustment. There is still one problem that the hydrophilic carbon dots could hardly be applied in the electroluminescent devices. Hence, we presented a one-pot synthesis of hydrophobic carbon dots modified by oleamine. The -NH₂ in oleamine reacted with the carboxyl group on the surface of carbon dots through amidation reaction. Therefore, the long-chain alkanes of oleamine could be modified on the surface of carbon dots to obtain the hydrophobic carbon dots. The deep blue emission of carbon dots was retained, which was further applied in the deep blue emissive electroluminescent devices.

Key words： carbon dot surface modification deep blue emission electroluminescent device
