| titleOfInvention | A kind of red long-afterglow phosphor and preparation method thereof |
| abstract | The invention discloses a kind of red long-afterglow phosphors and preparation method thereof, it is desirable to provide a kind of phosphor material powder with red long-afterglow luminescent properties belongs to phosphor technologies field.The chemical composition general formula of the fluorescent powder is Sr 3‑x‑y SiAlO 5 Cl 3 : x Eu 2+ , y Re 3+ , wherein Re is Dy, and one or more of Gd and Nd are combined, and the value range of x and y are respectively as follows: 0.01≤x≤0.05,0.01≤y≤0.10.The centre of luminescence of the fluorescent powder is Eu 2+ Ion, by introducing Dy 3+ , Gd 3+ And Nd 3+ Equal rare earth impurities ion can effectively enhance its long afterglow effect.Long lad phosphor provided by the invention has the characteristics that chemical stability is good, after-glow brightness is high, persistence is long, can be used for the fields such as decoration, emergency display. |
