Abstract: The coupling polarisation P_Er³⁺:NP of LSPR was investigated using the 20Li₂O-xBi₂O₃-(78-x)TeO₂-1Er₂O₃-1Ag glass system with electrical polarisability of spherical particle χ and Clausius-Mosotti relation polarisability α_L approximations. The maximum coupling polarisation P_Er³⁺:NP is suggested at x = 5 mol% implied from high χ and α_L at that region hence can contribute to maximum LSPR before an opposite pattern between both χ and α_L is observed at x = 11 mol%. The opposite pattern at x = 11 mol% is elucidated by determining the difference in contribution of electronic polarisability α_e to α_L and molar cation polarisability α_m with oxide ion polarisability a_o^2- to χ respectively.
