| titleOfInvention | A kind of twilight sunset tunable radiation emitting material and preparation method thereof and use its LED light device |
| abstract | The present invention relates to a kind of twilight sunset tunable radiation emitting material and preparation method thereof and use its LED light device, luminescent material is by matrix element Ln, divalence Eu elements are activator and B and Cl elements are what coactivator was formed, coactivator forms the trap that can capture electronics or hole in luminescent material, the brightness of luminescent material twilight sunset is adjusted by varying activator and/or coactivator ratio shared in luminescent material, the glow color of luminescent material twilight sunset is adjusted by varying the species and/or dosage for the matrix element Ln for forming luminescent material, wherein Ln is Al, Si, Ga, S, Mg, Ca, Sr, one or more in Ba.The luminescent material of the present invention can produce long-persistence luminous when excitation source stops and exciting, AC DC is changed without subsidiary rectifier when applied to alternating-current direct driving circuit, long afterglow can make up in an ac cycle LED caused by current cycle changes and shine the phenomenon that dies down, so as to keep light output to stablize. |
