Abstract
In this work, the two-phase Sr2+-doped LaVO4:Eu3+ nanomaterials were constructed through a facile hydrothermal approach. The crystal phase, morphology and optical performance were systematically investigated in detail. The results manifested that the dopant Sr2+ ions were doped into the host lattice, restricting the growth of grain and elevating the fluorescence intensity simultaneously. The morphology evolution process and optical performance modulation were also fully analysed. The fluorescence quenching was attributed to the adsorption of Cu2+ ions onto the matrix surface by electrostatic attraction and succeeding energy transfer from Eu3+ to Cu2+. Moreover, the materials displayed an excellent detecting ability for Cu2+ with high selectivity and sensitivity (0.514 μM and 0.476 μM for both two-phase samples). Consequently, this material could be applied as a promising candidate for Cu2+ detection due to good reusability and facile synthesis.
