Carbon nanoparticle ionic liquid hybrids and their photoluminescence properties

A fluorescent carbon nanoparticle ionic liquid hybrids (CNPIL) with high conductivity is synthesized by a facile one-step microwave method from ionic liquid 1-butyl-3-methylimidazolium glutamine salt and Glucose. This CNPIL exhibits excellent PL properties: bright and colorful PL covering the entire visible–NIR spectral range, up conversion PL properties, pH dependent and can be controlled by the reaction condition.
