Abstract
Description
1. | 将金属镓溶解于一酸溶液形成三价镓(例如硝酸镓)的第一水溶液,其中镓的量被调节至例如超过组份Ia化学计量量的0.1至7%的范围。或者,镓的量可被调节至例如超过组份Ia化学计量量的1至7%的范围。 |
2a. | 溶解一可溶性铕盐(例如,硝酸铕)形成第二水溶液,并将该第二溶液添加至该第一溶液中形成第三水溶液。该掺杂剂的量被调节至例如组份Ia化学计量量的1至4%的范围。 |
2b. | 使用碱(例如氢氧化铵)沉淀上述金属盐以生成凝胶状固体。例如:Ga(NO3)2+Eu(NO3)2→Ga(OH)3/Eu(OH)3↓ |
3a. | 在一单独反应器中,将一可溶性钙盐(例如硝酸钙)及(如果按式I推测)一可溶性锶盐(例如硝酸锶)溶解于稀硝酸中。 |
3b. | 使用硫酸沉淀出呈晶体形式的金属盐。例如:Ca(NO3)2/Sr(NO3)2+H2SO4→CaSO4/SrSO4↓。此可使用预制CaSO4和SrSO4粉末来代替。 |
4 | 混合自步骤2b和3b得到的固体,干燥所得固体并将所述固体磨成粉状。可将所得固体混合于悬浮液中。 |
5 | 在例如自500至850℃的温度及硫化氢气氛下将混合固体焙烧例如5小时。或者,此温度可为700至750℃,或650至750℃,或680至720℃。 |
6 | 在例如750至950℃或750至850℃或780至820℃的温度下采用一加热步骤,通常为一单独的加热步骤,以提高步骤5产物的结晶。该时间段通常短于第一焙烧时间段,例如可为2小时。可在第二次焙烧前重新研磨步骤5所得产物。 |
