Process for preparing solid red-to-yellow conversion copolymer system |
| abstract |
The invention discloses a preparation method of a solid red-to-yellow up-conversion copolymer system, which takes α -hydroxyethyl methacrylate (HEMA) and 3- (methacryloyloxy) propyl trimethoxy silane (TMSPMA) as monomers, and evenly coats a sensitizer (sandwich type palladium phthalocyanine) and a luminescent agent (rhodamine series compound) in a certain ratio by in-situ polymerization under the initiation of azoisobutyronitrile to obtain the solid red-to-yellow up-conversion silicon copolymer, thereby solving the problem that deoxidization is needed in a solution state, more importantly solving the bottleneck problem that the current solid polymer has low up-conversion efficiency under the excitation of a 655nm semiconductor laser (laser power density is 1W × cm) ‑2 ) Up-conversion efficiency (F) of the solid copolymer obtained by the present invention UC ) Up to 12.75%; and in the air atmosphere, the conversion efficiency value on the solid can be kept more than 4 days to be almost not attenuated; has application value in the field of solar energy utilization. |
