- •
A control of the Nd3+ emission by polarization dependent plasmon-mode of Ag Np chains is achieved.
- •
The polarized spectra of the plasmon modes associated with Ag NPs distributed in long linear chains on LiNbO3 are calculated.
- •
Exciting the radiative mode of the Ag chains with light polarized parallel to their axis selects the π-Stark transitions of Nd3+ ions.
- •
The results are relevant for potential devices with generation of coherent radiation at the nanoscale.
