Abstract
This article reports on the newly developed heavy metal based multicomponent ZrF4-BaF2-LaF3-YF3-AlF3-NaF optical glass systems, which are abbreviated as ZBLYAN glasses for easy reference. These host glass matrices have been doped with rare earth ions such as Pr3+ or Dy3+ or Tm3+ to understand their upconverted emission phenomenon and normal emission as well through a systematic approach. NIR upconversion emissions into visible colours have been reported from these rare earth ions doped optical fibre core based standard glass compositions. The possible mechanisms involved in such upconversion emission processes have been explained more clearly in terms of energy levels schemes.
