Ho:GDVO4 is a crystalline solid used as a semiconductor and in photo optic applications. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement. Holmium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f116s2. In its elemental form holmium's CAS number is 7440-60-0. The holmium atom has a radius of 174.3.pm and it's Van der Waals radius is unknown. Holmium has the highest magnetic moment (10.6µB) of any naturally occurring element. Because of this it has been used to create the highest known magnetic fields by placing it within high strength magnets as a pole piece or magnetic flux concentrator. This magnetic property also has value in yttrium-iron-garnet (YIG) lasers for microwave equipment. Holmium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Holmium lases at a human eye safe 2.08 microns allowing its use in a variety of medical and dental applications in both yttrium-aluminum-garnet (YAG) and yttrium-lanthanum-fluoride (YLF) solid state lasers. The wavelength allows for use in silica fibers designed for shorter wavelengths while still providing the cutting strength of longer wave length equipment. Gadolinium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f75d16s2. In its elemental form gadolinium's CAS number is 7440-54-2. The gadolinium atom has a radius of 178.7.pm and it's Van der Waals radius is unknown. Gadolinium is utilized for both its high magnetic moment (7.94µB) and in phosphors and scintillator material. When complexed with EDTA ligands, it is used as an injectable contrast agent for patients undergoing magnetic resonance imaging. Gadolinium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.

With its high magnetic moment, gadolinium can reduce relaxation times and thereby enhance signal intensity. The extra stable half-full 4f electron shell with no low lying energy levels creates applications as an inert phosphor host. Gadolinium can therefore act as hosts for x-ray cassettes and in scintillator materials for computer tomography. Vanadium is a Block D, Group 5, Period 4 element. The electronic configuration is [Ar] 3d3 4s2. In its elemental form vanadium's CAS number is 7440-62-2. The vanadium atom has a radius of 131.1.pm and it's Van der Waals radius is 200.pm. Vanadium is highly resistant to corrosion, so it is commonly used to alloy stainless steel grades. Vanadium compounds are used in advanced ceramics. Vanadium is a petrochemical cracking catalyst. Vanadium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.
