| Abstract: | The influence of the isostatic oxygen pressure as a crystal growth atmosphere on the optical and structural properties of undoped and erbium‐doped calcium orthovanadate single‐crystal fibres was studied by optical absorption, photoluminescence, energy‐dispersive X‐ray analysis and X‐ray powder diffraction techniques. Relationships between the oxygen pressure used during the crystal growth and some optical and structural parameters are established. Through an oxygen vacancy model the effects of the crystal growth conditions on the physical properties of the material are inferred. Copyright © 2000 John Wiley & Sons, Ltd. |
