| titleOfInvention | Rare-earth doped alkaline-earth silicon nitride phosphor, method for producing and radiation converting device comprising such a phosphor |
| abstract | THE INVENTION RELATES TO A METHOD OF MANUFACTURING A RARE-EARTH DOPED ALKALINE-EARTH SILICON NITRIDE PHOSPHOR OF A STOICHIOMETRIC COMPOSITION. SAID METHOD COMPRISING THE STEP OF SELECTING ONE OR MORE COMPOUNDS EACH COMPRISING AT LEAST ONE ELEMENT OF THE GROUP COMPRISING THE RARE-EARTH ELEMENTS (RE), THE ALKALINE-EARTH ELEMENTS (AE), SILICON (SI) AND NITROGEN (N) AND TOGETHER COMPRISING THE NECESSARY ELEMENTS TO FORM THE RARE-EARTH DOPED ALKALINE-EARTH SILICON NITRIDE PHOSPHOR (AE2SI5N8:RE). THE METHOD FURTHER COMPRISES THE STEP OF BRINGING THE COMPOUNDS AT AN ELEVATED TEMPERATURE IN REACTION FOR FORMING THE RARE-EARTH DOPED ALKALINE-EARTH SILICON NITRIDE PHOSPHOR (AE2SI5N8:RE). IN SUCH A METHOD NORMALLY A SMALL AMOUNT OF OXYGEN, WHETHER INTENTIONALLY OR NOT-INTENTIONALLY ADDED, WILL BE INCORPORATED IN THE RARE-EARTH DOPED ALKALINE-EARTH SILICON NITRIDE PHOSPHOR (AE2SI5N8:RE). ACCORDING TO THE INVENTION THE CREATION OF DEFECTS BY FORMATION OF A NON-STOICHIOMETRIC OXYGEN CONTAINING PHOSPHOR IS AT LEAST PARTLY PREVENTED BY PARTLY SUBSTITUTING FOR THE IONS (AE, SI, N) OF THE ALKALINE-EARTH SILICON NITRIDE PHOSPHOR (AE2SI5N8:RE) SUITABLE FURTHER ELEMENTS OF THE PERIODIC SYSTEM BY WHICH VACANCIES ARE CREATED, FILLED OR ANNIHILATED RESULTING IN THE FORMATION OF A MODIFIED ALKALINE-EARTH SILICON NITRIDE PHOSPHOR (AE2SI5N8:RE) HAVING A STOICHIOMETRIC COMPOSITION. IN THIS WAY A MODIFIED PHOSPHOR IS OBTAINED HAVING EXCELLENT AND STABLE OPTICAL PROPERTIES. THE INVENTION FURTHER RELATES TO A MODIFIED PHOSPHOR OBTAINABLE BY THE ABOVE-MENTIONED METHOD AND A RADIATION CONVERTING DEVICE COMPRISING SUCH A PHOSPHOR. |
