Laser Spectroscopy of Rare Earth Oxides
Recent developments in the spectroscopy of the rare earth oxides using laser techniques are reviewed. A Ligand Field theoretical approach describing the electronic states is outlined along with the various experimental techniques that have been used as diagnostic tools to test various aspects of the theory. Results for several molecules are outlined. INTRODUCTION The emission and absorption spe...

متن کاملRare earth element oxides for tracing sediment movement
The development of soil conservation plans and evaluation of spatially distributed erosion models require knowledge of rates of soil loss and sedimentation on different landscape elements and slope positions. Characterization of soil erosion rates and patterns within watersheds is important for the understanding of erosion processes and landscape evolution. Experimental data that show spatial t...
متن کاملPressureless Sintering of Si3N4 Ceramic Using AlN and Rare-Earth Oxides
Using intermediate, liquid-forming compositions in the approach focuses on the Si3N4–R2O3 binary, where R2O3 is any (Y,La)2O3–AlN system as additives, fully dense Si3N4 ceramrare-earth oxide (or Y2O3) used singly or severally. After sinics with high strength at high temperature have been tering, this composition forms -Si3N4 and some refractory rareobtained by pressureless sintering. The cerami...
