Morphological changes during dehydration of single crystals containing lattice H2O (hydrates) can be dramatic, leading to surfaces that are rough, polycrystalline, and laden with defects. Previous studies have shown that ionic crystal surfaces containing point defects readily desorb energetic positive ions under UV excimer laser irradiation. In this work, we examine the consequences of exposing thermally pretreated single crystal brushite (CaHPO4∙2H2O) to 30 ns pulses of 248 nm laser irradiation and show that the surface modifications strongly enhance the emission of Ca+ and other positive ions. © 2000 American Institute of Physics.
