WebA novel red-emitting phosphor LiY9(SiO4)(6)O-2:Eu3+ has been synthesized by a high-temperature solid-state reaction. X-ray powder diffraction (XRD) analysis confirmed the phase formation of LiY9(SiO4 Although phosphorus (15P) has 22 isotopes from P to P, only P is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are P with a half-life of 25.34 days and P with a half-life of 14.268 days. All others have half-lives of under 2.5 minutes, most under a second. … See more Phosphorus-32 P, a beta-emitter (1.71 MeV) with a half-life of 14.3 days, is used routinely in life-science laboratories, primarily to produce radiolabeled DNA and RNA probes, e.g. for use in See more • Phosphorus isotopes data from The Berkeley Laboratory Isotopes Project's See more
