Abstract

An increase in the intensity of photoluminescence spectra of organic phosphor with terbium Tb³⁺ ions intruded into a 3D photonic crystal, i.e., SiO₂ opal matrix, is established. The superluminescence effect is observed upon excitation at a wavelength of 369 nm at the ⁵D₄–⁷F₅ transition in Tb³⁺ ion in the green spectral region (λ = 545 nm). Lasing feasibilities in the composite opal matrix for the ⁵D₄–⁷F₅ transition in Tb³⁺ ion are analyzed.

球状光子晶体孔中的Organic有机组成的光致发光

摘要

建立了具有掺入Tb ³⁺离子的3D光子晶体（即SiO ₂蛋白石基质）的有机荧光粉的光致发光光谱强度的增加。在绿色光谱区（λ= 545 nm）中，Tb ³⁺离子在⁵ D ₄ – ⁷ F ₅跃迁处以369 nm的波长激发时，观察到超发光效应。分析了复合蛋白石基质中Tb ³⁺离子中⁵ D ₄ – ⁷ F ₅跃迁的发射可行性。
