In situ immobilization of YVO4:Eu phosphor particles on a film of vertically oriented Y2(OH)5Cl·nH2O nanosheets†
Abstract
A heterostructured photoluminescence ‘turn-off’ film was developed using vertically oriented LYH:Eu nanosheets as a partial sacrificial layer for isolated YVO4:Eu3+ nanophosphor layers and was used for the convenient detection and removal of Cu2+ ions with excellent sensitivity and recyclability.
