【摘要】 在具有翡翠成份的原料中掺入0.01～0.1mol的Eu₂O₃、Dy₂O₃、CeO₂,经商温高压合成,分别茯得可发红、黄、紫色可见荧光的翡翠宝石。由于翡翠非对称晶场的作用,Eu³⁺的电偶极跃迁⁵D₀→⁷F₂成为发光主峰,Dy³⁺的发光峰出现明显劈裂,增大Ce³⁺的掺杂量,出现浓度猝灭现象。更多还原

【Abstract】 A jadeite gem having visible emission （red, yellow, violet） has been synthesized by doping Eu₂O₃, Dy₂O₃, CeO₂ of 0.01-0.1 mol under high pressure and high temperature. Their emission spectra were determined. Because of the non-symmetry crystal field in jadeite, the electric dipole transition ⁵D₀→⁷F₂ of Eu³⁺ becomes major emission; and the luminescence peaks of Dy³⁺ split. With the increasing of the amount of Ce³⁺, the concentration quenching effect occurs.更多还原
