Break the Interacting Bridge between Eu(3+) Ions in the 3D Network Structure of CdMoO(4): Eu(3+) Bright Red Emission Phosphor

Eu(3+) doped CdMoO(4) super red emission phosphors with charge compensation were prepared by the traditional high temperature solid-state reaction method in air atmosphere. The interrelationships between photoluminescence properties and crystalline environments were investigated in detail. The 3D ne...

description Eu(3+) doped CdMoO(4) super red emission phosphors with charge compensation were prepared by the traditional high temperature solid-state reaction method in air atmosphere. The interrelationships between photoluminescence properties and crystalline environments were investigated in detail. The 3D network structure which composed by CdO(8) and MoO(4) polyhedra can collect and efficiently transmit energy to Eu(3+) luminescent centers. The relative distance between Eu(3+) ions decreased and energy interaction increased sharply with the appearance of interstitial occupation of O(2−) ions ([Formula: see text] ). Therefore, fluorescence quenching occurs at the low concentration of Eu(3+) ions in the 3D network structure. Fortunately, the charge compensator will reduce the concentration of [Formula: see text] which can break the energetic interaction between Eu(3+) ions. The mechanism of different charge compensators has been studied in detail. The strong excitation band situated at ultraviolet and near-ultraviolet region makes it a potential red phosphor candidate for n-UV based LED.
