Pressure tuning optical absorption spectroscopy of erbium-doped silicon nanocrystals

Article Abstract:

High-pressure optical absorption spectroscopic measurements of both erbium-doped and undoped Si nanoparticles are carried out in a diamond anvil cell. Doped nanocrystals maintain a significant elevation in the phase transition pressure, but the Er dopant does not introduce the type of structural defects that would lower the energy barrier to such a transformation.

Enhanced luminescence of an erbium(III) ion-association ternary complex with a near-infrared dye

Article Abstract:

The enhanced near-infrared (NIR) photoluminescence of erbium ion has been achieved from the erbium ion-association ternary complex sensitized by the near-infrared dye IR5 upon 488 nm excitation and upon 980 nm excitation. The results indicate that the complex has promising applications in erbium-doped optical materials.

Linear and nonlinear optical properties of an erbium two-photon dye salt

Article Abstract:

The nonlinear optical properties of a new chromophore erbium two-photon dye salt are studied in THF solution. The theoretical analysis shows a 3 order of magnitude increase in the intersystem crossing rate due to the presence of erbium.
