摘要

在60Co源3000 R/s γ辐射场和场外,在350 ~ 500℃的温度下,在NaNO3和cno3盐的碱性熔体中对K8玻璃进行低温热处理。在\({\text{Na}}_{{{\text{glass}}}}^{ + }\)↔\({\text{Cs}}_{{{\text{melt}}}}^{ + }\)离子交换扩散引起的热辐射处理的影响下,在玻璃的表层产生机械压应力,导致形成给定厚度的波导层,并增加折射率(RI)增量、波导模式数和波导层的深度。

Formation of Waveguide Layers on the Surface of K8 Glass Produced by Thermoradiation Ion Exchange

Formation of Waveguide Layers on the Surface of K8 Glass Produced by Thermoradiation Ion Exchange

The low-temperature heat treatment of K8 glass is carried out at temperatures of 350–500°C in alkaline melts of NaNO3 and CsNO3 salts in the field of gamma radiation from the 60Co source at the dose rate of 3000 R/s and also outside the field. Under the influence of thermoradiation treatment due to the \({\text{Na}}_{{{\text{glass}}}}^{ + }\)\({\text{Cs}}_{{{\text{melt}}}}^{ + }\) ion-exchange diffusion, mechanical compressive stresses are created in the surface layer of the glass, which lead to the formation of a waveguide layer of the given thickness and an increase in the refractive index (RI) increment, the number of waveguide modes, and the depth of the waveguide layer.
