Abstract
Orthorhombic and hexagonal CeOHCO3 crystals were grown by a hydrothermal me thod. X-ray diffraction, scanning electron microscopy and optical spectrosc opy were used to characterize the samples. The orthorhombic phase was forme d prior to the hexagonal phase following an increase in temperature. The tw o phases correspond to different morphologies and luminescent performance. Orthorhombic CeOHCO3 crystals are shuttle-like while hexagonal CeOHCO3 is b utterfly-like, and the former displays a much stronger luminescence than th e latter, (C) 2000 Published by Elsevier Science B.V.
