| titleOfInvention | Acidic nitride-based fluorescent material and white light emitting apparatus using same |
| abstract | The oxynitride-based phosphor represented by the following formula (1) having an orthorhombic crystal structure is excited by near ultraviolet or blue light to emit red or yellow-red light, and has a different lattice constant than the conventional crystal structure. The photoluminescence efficiency is improved and the luminance is excellent, and the photoluminescence efficiency hardly decreases even under severe conditions such as high temperature and high humidity. Accordingly, the white light emitting device including the phosphor can emit warm white light with higher luminance than the conventional one, and has excellent color rendering, color reproducibility and color control: [Formula 1] AAlSiN 3 :zEu 2+ In the above formula, A is Sr, Ba or a combination thereof, 0.001≤z≤0.3. |
