Abstract

Efficient method for the directed synthesis of ZrO₂–Er₂O₃ luminescent material in nanocrystalline state has been developed. Monodisperse samples of cubic modification with particle size from 5 to 71 nm depending on synthesis conditions have been synthesized. Luminescence spectra due to ⁴I_11/2 → ⁴I_15/2 and ⁴I_13/2 → ⁴I_15/2 transitions of Er³⁺ ions have been registered upon their excitation by 532-nm radiation. Upconversion luminescence spectra due to ²H_11/2, ⁴S_3/2 → ⁴I_15/2, ⁴F_9/2 → ⁴I_15/2 transitions have been registered on excitation to level ⁴I_13/2 of Er³⁺ ions by 1550-nm radiation.

摘要

已经开发出一种用于定向合成纳米晶态ZrO ₂ -Er ₂ O ₃发光材料的有效方法。根据合成条件，合成了粒径为5至71 nm的立方改性单分散样品。发光光谱由于^4个我_11/2 → ⁴我_15/2和⁴我_13/2 → ⁴我_15/2尔过渡³⁺离子已经通过532纳米的辐射在它们的激发注册。由² H ₁₁ / ^2，4引起的上转换发光光谱小号_3/2 → ⁴我_15/2，⁴ ˚F _9/2 → ^4个我_15/2跃迁已经登记在激励电平⁴我_13/2铒³⁺由1550nm的辐射离子。
