Effects of Ge concentration, boron co-doping, and hydrogenation on fiber bragg grating characteristics
(2005)In this paper, we compare photosensitivity, refractive-index modulation depth, spectral bandwidth, and excess loss through the inscription of fiber Bragg gratings in unloaded and hydrogen-loaded fibers with low- or ...

Spectroscopic investigations on the effect of humic acid on the formation and solubility of secondary solid phases of Ln2(CO3) 3
(2011)The formation of secondary Ln(III) solid phases (e.g., Nd 2(CO3)3 and Sm2(CO3) 3) was studied as a function of the humic acid concentration in 0.1 mol/L NaClO4 aqueous solution in the neutral pH range (5-6.5). The solid ...
