Optical properties of Nd3+ doped ionic liquid immobilized on mesoporous silica support.
The synthesis of a new material based on Nd3+ ions doped into an imidazolium-type ionic liquid with further immobilization on a mesoporous silica support is reported. The material was investigated by DR-UV/VIS, FT-IR, thermogravimetric analysis, N2 adsorption measurements and time-resolved photoluminescence spectroscopy. The intensity of the near-infrared emission of Nd3+ was weak and the lifetime measured at about 910 nm was 7 micros.
