在稀土掺杂的Y2O3层中观察到了电致发光，其发光颜色从Eu3+的红色到Tm3+的蓝色。在3−5×104V/cm的电场下，在直流激励下，Y_2O_3：Tb~(3+)的发光亮度约为1fl，效率约为2×10~(-4)。样品对交流激励也有反应。为了研究发射机理，测量了发射的暂态行为。
Electroluminescence has been observed in rare earth-doped Y2O3powder layers with various emission colors spanning a spectrum from red in case of Eu3+to blue in case of Tm3+. The brightness of about 1 fL and efficiency of about 2×10-4were obtained for Y2O3: Tb3+with dc excitation under the electric field of 3−5×104V/cm. Samples were also responsive to ac excitation. To investigate the emission mechanism, the transient behaviour of the emission has been measured.
