Abstract: IR luminescence and absorption in bismuth-doped silica glass-core fibers observed recently (see [arXiv:1106.2969v1 [physics.optics]) are argued to be caused by transitions in interstitial Bi...
Testing the diffusion hypothesis as a mechanism of self-healing in Disperse orange 11 doped in PMMA
hypothesis self-healing
2011/9/1
In this work, we show that reversible photodegradation of Disperse Orange 11 doped in PMMA is not due to dye diffusion – a common phenomenon observed in many dye-doped polymers. The change in linear a...
