Strong green fluorescent hydrogels with Ba2MgSi2O7:Eu2+phosphor embedded in cellulose.
Non-cytotoxic and green-emitting fluorescent hydrogels were constructed from a cellulose solution containing Ba2MgSi2O7:Eu2+green phosphor in a NaOH/urea aqueous system. The structure, optical properties and cytotoxicity of these hydrogels were studied. The Ba2MgSi2O7:Eu2+phosphor particles were dispersed evenly in the cellulose hydrogel matrix. Good luminescent properties of Ba2MgSi2O7:Eu2+phosphor were maintained in the hydrogels, leading to strong green emission under ultraviolet excitation. Fluorescent hydrogels have no obvious cytotoxicity in a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) proliferation test, and have potential use in in vivo applications like optical imaging and drug delivery.
