| Abstract: | A novel red phosphor NaLa4(SiO4)3F: Eu3+ was synthesized by the conventional solid-state reaction at 950 °C for the first time. The luminescence properties of NaLa4(SiO4)3F: Eu3+ were investigated, and the critical concentration of the activator concentration (Eu3+) was found to be 0.1 mol per formula unit. The phosphor presented red luminescence under the ultraviolet excitation of 254 or 395 nm, attributed to the transitions from 5D0 excited states to 7FJ ( J = 0-4) ground states of Eu3+ ions. The results indicated that this newly-developed phosphor could find applications in tricolor fluorescent lamp, phosphor-liquid crystal displays and white lighting devices utilizing GaN-based excitation in the near UV. |
