Abstract

This study demonstrates manipulation of luminance from CaF₂: Yb³⁺, Er³⁺ up-conversion (UC) micronano particles emissions and the fluorescence intensity improvement by using various surface plasmon resonance substrates which consist of SiO₂, gold thin film, and nano cones from bottom to the top in the view of side structure. When they are applied, the optimum enhancement of the intensity of red up-conversion luminescence (UCL) peaked at 653 nm shows up to 189-fold. The distance dependent intensities of two UC micro-nano particles manipulated by holographic optical tweezers (HOT) are also illustrated in this article. The fluorescence intensities decrease when two UC micro-nano particles become near to the each other due to the inter-system transition at the much short distance.
