| titleOfInvention | Compound upper conversion nano crystalline substance of silver-colored graphene coated silica and preparation method thereof |
| abstract | The present invention relates to compound upper conversion nano crystalline substance of a kind of silver-colored graphene coated silica and preparation method thereof.The silver/graphite alkene@SiO that the present invention is obtained 2 ‑NaLuF 4 :Yb, Gd, Er composite fluorescent nano particle, the nanocrystalline structure is to be supported on Graphene as kernel with silver, then with coated with silica, conversion nano is brilliant in silica surface connection.The present invention improves the brilliant luminous intensity of upper conversion nano by the metal-enhanced fluorescence effect of noble silver.Meanwhile, silver is supported on Graphene, can very well prevent Argent grain from reuniting, there is field-effect superposition because distance is near in the Nano silver grain being dispersed and fixed on Graphene, mutual polarity and surface plasma resonance mutually strengthen；Simultaneously because Graphene is a kind of excellent electron acceptor and conductor, its electron density is reduced after the electric charge of Nano silver grain is shifted to Graphene, effective dielectric constant increases, and making the surface plasma resonance of Nano Silver strengthens, and causes the metal-enhanced fluorescence effect of Nano Silver stronger.The method makes the Up-conversion Intensity of rare earth upconversion nano crystal improve about 50 times. |
