Abstract

Abstract In this work, The TBS glass microspheres doped with Er 3+ for morphology-dependent resonances of upconversion emission were designed. The glass sample components are 25TiO 2–27BaCO 3–8Ba(NO 3) 2–6ZnO 2–9CaCO 3–5H 3BO 3–10SiO 2–7water glass-3Er 2O 3 (wt%), and the emission spectra of TBS glass and a TBS glass microsphere (about 48 μm in diameter) were measured under 633 nm excitation and discussed. The strong morphology-dependent resonances of upconversion luminescences in the microsphere were observed. The observed resonances could be assigned by using the well-known Lorenz–Mie Formalism.
