The coupling polarisation PEr 3+:NP of LSPR was investigated using the 20Li2O-xBi2O3-(78-x)TeO2-1Er2O3-1Ag glass system with electrical polarisability of spherical particle χand Clausius-Mosotti relation polarisability αL approximations. The maximum coupling polarisation PEr 3+:NP is suggested at x = 5 mol% implied from high χand αL at that region hence can contribute to maximum LSPR before an opposite pattern between both χand αL is observed at x = 11 mol%. The opposite pattern at x = 11 mol% is elucidated by determining the difference in contribution of electronic polarisability αe to αL and molar cation polarisability αm with oxide ion polarisability ao 2- to χrespectively. © 2023 Inderscience Enterprises Ltd.
