We have developed a ratiometric time-gated luminescence sensory system for hypochlorous acid(HClO)based on europium and terbium complexes-doped silica nanoparticles.
The Lattice Boltzmann model of coupling mass transfer(LBM)was used from the micro perspective to simulate the leaching process of ionic type rare earth ore to analysis of the macro regularity.
LiYF4 nanocrystals with the tetragonal structure have been adopted as the host materials for the phosphors and scintillators owing to the low phonon energy and high optical transparency.
The pure phases of Ce3+-activated La3Si6N11 yellow phosphors were synthesized by high temperature solid-state method by adjusting the condition of sintering.
A series of luminescent emission-tunable phosphors Ca12Al14O32F2:Tb3+,Eu2+,Eu3+have been synthesized by a high temperature solid-state reaction in a reductive atmosphere.The sample phase was determine
