Abstract

Concentration controlled, nanocrystalline Er doped Y2SiO5 particles were fabricated. Using 2-level model the cooperative upconversion coefficient was determined. We find that Er-doped YSO has much lower cooperative upconversion than silica, enabling it to achieve population inversion within a reasonable limit.
