A series of novel cellulose-based hybrid hydrogels were prepared through cellulose and fluorescer Tb3+ doped Y4Si2O7N2 (YT) in NaOH/urea aqueous solution using epichlorohydrin (ECH) as a cross-linker. The structure and properties were characterized by wide-angle X-ray diffraction (XRD), scanning electron microscopy (SEM), FT-IR and fluorescence spectroscopy, as well as by swelling ratio measurements and compression tests. The results revealed that the green fluorescence intensity of the cellulose-based hybrid hydrogels became stronger with an increase of YT contents. The hybrid hydrogels exhibited homogeneous porous structures and the YT particles were tightly embedded in the macroporous cellulose matrix. When the content of YT particles was 0.02 g, the cellulose-based hybrid hydrogels (YTCH3) exhibited stronger fluorescence intensity, higher compressive strength and modulus, and lower swelling ratio.
