Here, we present the results of the analysis of Sm3+or Dy3+(0.5mol%) ions doped heavy metal oxide (HMO)-based zinc lead borate (ZLB) glasses. Optical measurements such as absorption, emission spectra, lifetimes, XRD, DSC profiles have been carried out. The emission spectrum of Sm3+:ZLB has shown the emission transitions of4G5/2→6H5/2(563nm),4G5/2→6H7/2(598nm),4G5/2→6H9/2(646nm),4G5/2→6H11/2(708nm) with λexc: 401nm (6H5/2→4F7/2). In the case of the Dy3+:ZLB glass, emission transitions of4F9/2→6H15/2(485nm),4F9/2→6H13/2(575nm) and4F9/2→6H11/2(664nm) with λexi: 447nm (6H15/2→4I15/2) have been identified. Energy level schemes relating to the emission mechanisms involved in Sm3+and Dy3+glasses have been given.
