Title: | Large-area color controllable remote carbon white-light light-emitting diodes | Authors: | Zhang, W Yu, SF Fei, L Jin, L Pan, S Lin, P |
Issue Date: | 2015 | Publisher: | Pergamon Press | Source: | Carbon, 2015, v. 85, p. 344-350 How to cite? | Journal: | Carbon | Abstract: | We disperse carbon nanodots (C-dots), which can be achieved by decomposing organic acid in silane coupling agent, in epoxy oligomer to realize large-area C-dots film on any transparent substrate. Due to the similarity in solubility parameters between C-dots and epoxy resin, aggregation of C-dots in epoxy resin is suppressed. It is found that the C-dots films can support high conversion efficiency (>60%) white-light emission under 460 nm illumination. In addition, the corresponding correlated color temperature can be varied between 2500 and 10,000 K by controlling the thickness of the C-dots film. We also verify that the absolute performance of C-dots film is compatible with that of the commercial available phosphor film. | URI: | http://hdl.handle.net/10397/8565 | ISSN: | 0008-6223 | EISSN: | 1873-3891 | DOI: | 10.1016/j.carbon.2014.12.107 |
