Abstract

In the present work, interaction of a low-energy (~ 40 keV) He⁺ ion beam with silver-ion-exchanged glasses is studied. It is found that the interaction leads to increase of index of refraction and optical density of the interaction area of the samples, and at the same time, results in quenching of luminescence radiation of the interacted area on the samples. A remarkable dispersion for the index of refraction (n = n(λ)) is observed. Maximum change in the index of refraction occurs for the wavelength very close to the wavelength of the red-shifted surface plasmon resonance of the silver nanoclusters embedded in the glass matrix. Photoluminescence spectra studies show that interaction of silver-ion-exchanged glasses with low-energy He⁺ beam results in reduction of ionic silver clusters to the neutral ones, which is accompanied with increase of the index of refraction. That is, the produced neutral silver nanoparticles increase the index of refraction of the interacted area on the samples. Such manipulation of the index of refraction has potential for manufacturing miniaturized phase optical diffractive elements.

与低能He +束相互作用导致银离子交换玻璃的折射率变化和光致发光猝灭

摘要

在目前的工作中，研究了低能（〜40 keV）He ⁺离子束与银离子交换玻璃的相互作用。发现相互作用导致样品相互作用区域的折射率和光密度的增加，并且同时导致样品上相互作用区域的发光辐射的猝灭。观察到折射率有明显的色散（n  =  n（λ））。对于非常接近嵌入在玻璃基质中的银纳米团簇的红移表面等离子体激元共振的波长的波长，发生折射率的最大变化。光致发光光谱研究表明，银离子交换玻璃与低能氦的相互作用⁺束导致离子银团簇减少至中性团簇，这伴随着折射率的增加。即，产生的中性银纳米颗粒增加了样品上相互作用区域的折射率。折射率的这种操纵对于制造小型化的相位光学衍射元件具有潜力。
