摘要：
A systematic study of the preparation of lanthanide (Eu3+, Tb3+, Sm3+ and Dy 3+) phosphors was carried out and luminescent materials (red, green, orange-red and blue-yellow) were successfully achieved at low temperature (70 degrees C) in 45 min, using simultaneous supersonic and microwave irradiation. Scanning and transmission electron microscopic images indicate that one-dimensional nanorods with diameters of 10-20 nm and lengths of up to 200 nm were formed. The phosphors were entrapped in cellulose gels and the corresponding hydrogels were also strongly emissive.
