| 摘 要： | 采用高温固相法在空气中合成了(Od,Lu)2O3,(Gd,Lu)2O3:Eu3+和(Gd,Lu)2O3:Tb3+系粉体.研究了二元系中Lu2O3的摩尔分数对抑制Gd2O3高温相变、粉体的发光性质和光谱性质的影响.结果表明:在(Gd,Lu)2O3系粉体中,当Lu2O3的摩尔分数(下同)大于40%时,能在煅烧温度不低于1 700℃情况下,抑制Gd2O3的相变得到利于制备透明陶瓷的立方相结构.而且随着Lu3+离子的浓度增加,先后观察到红移和蓝移现象;在(Gd,Lu)203:Eu3+系粉体中,粉体的发光强度随着Lu3+掺杂量增加而减小,Eu3+的最佳掺杂量为7%;在(Gd,Lu)2O3:Tb3+系粉体中,Tb3+离子的最佳掺量为1%.

| Abstract: | Three series of powders were prepared by high temperature solid-state method, namely (Gd, Lu)2O3, (Gd, Lu)2O3:Eu3+ and (Gd, Lu)2O3:Tb3+. The influences of mole fraction of Lu2O3 in binary system elements on the phase transformation of Gd2O3, and the optical properties and spectra characteristic of (Gd, Lu)2O3:Eu3+/Tb3+ powders were investigated. The results indicate that in the case of (Gd, Lu)2O3 series powders, when the mole fraction (the same below) of Lu2O3 is more than 40% and the calcination temperatu... |
