摘要：

A novel erbium-based compound as well as Er2O3 nanosheets have been synthesized through a simple hydrothermal route. The nanosheets are of 200 nm width and 10-15 nm thickness. It is suggested that this erbium-based compound has a possible formula of Er2O5H4 with a primitive tetragonal structure (cell parameters: a = 8.465(1) and c = 15.117(2) angstrom). Face-centered cubic and body-centered cubic structured Er2O3 nanosheets were obtained after calcination of this compound at 623 and 973 K, respectively, both having a paramagnetic behavior. Er2O5H4 and Er2O3 nanosheets have similar up-conversion properties with strong blue emission, which is rarely reported in the literature. The existence of absorbed surface contaminations in nanosheets might be the origin for the blue emission enhancement.
