| Popis | Preparation of LaF3:Gd3+ 30%, Ce3+ 10%, Eu3+ 1% NPs conjugated with CdTe quantum dots was performed by two methods. The first method includes mixing of two products, while the second method is based on the co-precipitation approach. The mixing of individual components did not lead to the formation of a new product. On the contrary, the product obtained by co-precipitation synthesis resulted in particles having about 140 nm in diameter. This nanocomposite system exhibits tunable red (lambda(exc) = 248 nm) and green (lambda(exc) = 340 m) luminescence due to the presence of Eu3+ ion and CdTe quantum dots. |
