STRONTIUM OXYORTHOSILICATE PHOSPHORS HAVING IMPROVED STABILITY UNDER A RADIATION LOAD AND RESISTANCE TO ATMOSPHERIC HUMIDITY |
摘要 |
<p>Exemplary embodiments of the present invention relate to inorganic phosphors based on silicate compounds having improved stability under a resulting radiation load and resistance to atmospheric humidity, which are capable of converting higher-energy excitation radiation, i.e. ultraviolet (UV) or blue light, with high efficiency into a longer-wavelength radiation which may be in the visible spectral range. A calcium molar fraction x having a value between 0 and 0.05 is added to a silicate phosphor having the general formula Sr3-x-y-zCaxMIIySiO5:Euz.</p> |
