Abstract –Recently, development of laser gain medium has been more attractive to be investigated due to the laser application in human daily life. For example, laser is used for medical treatment, surgery, security system, cutting, spectroscopy characterization and sensor. Laser is produced by the system including pump source, resonator, and an optical gain medium. This paper will be focused in a gain medium based on trivalent rare earth ions (Ln3+) such as Dy3+, Sm3+, and Eu3+ doped glass. The gain medium is developed by melt and quenching technique. The raw materials are a powder that is melted at the glass transition temperature. Afterwards, the glass liquid is poured at stainless steel at room temperature and annealed for several hours. After the annealing process, the bulk glass is cut and polished for characterization. Physical, optical, and luminescence properties of the gain medium are analyzed and discussed in this paper. The CIE 1931 chromaticity diagram coordinate is calculated to define the proper coordinate of glass sample emission light. The previous research shows that Dy3+, Sm3+ and Eu3+ in glass system can emit white, orange, and reddish-orange excited by 388 nm, 403 nm and 393 nm, respectively. From the results, trivalent rare earth ion doped glass possesses high potential to be developed for laser gain medium material. Keywords: glass, laser, luminescence, optic, Ln3+

The Rare Earth

By activation of the cubic garnet host lattice Gd3Te2Li3O12 with trivalent rare earth ions the most intense visible emission is observed for Ln3+ = Eu, Tb. Energy transfer from Gd3+ to Sm3+, Eu3+ or Dy3+, from Tb3+ to Eu3+ and from Er3+ to Tm3+ has been found to occur. The luminescence properties are strongly influenced by the substitution of Te6+ by W6+ (systems Gd3-xLnxTe2-yWyLi3O12)

Superconducting Phase Transition

Perovskites of type Sm 0.5 Re 0.5 Ba 2 Cu 3 O 7−δ (Re=Y, La, Nd, Eu, Gd, Dy, Ho, Er, Tm, Yb, and Lu) have been investigated by XRD, magnetic and EPR measurements in both orthorhombic and tetragonal phases. In the former case the usual superconducting phase transition in the range 90 to 95 K has been detected. In all the compounds an EPR spectrum of Cu 2+ ions has been observed. In the tetragonal phase, the EPR spectra of trivalent rare earth ions have been recorded for some members of the series. The observation of a broad EPR signal, tentatively attributed to superexchange interaction over the oxygen bridges < O 2), has also been recorded. Furthermore, the intensity of low-field microwave absorption has been found to depend strongly on the nature of the substituted rare earth ion at the sites of Y ions of the YBa 2 Cu 3 O 7−δ type compounds.

Quenching Phenomenon

The precursor prepared by co-precipitation method was sintered at various temperatures to synthesize crystalline manganese tungstate (MnWO4). Sintered MnWO4 showed the best crystallinity at a sintering temperature of 800 °C. Rare earth ion (Dysprosium; Dy3+) was added when preparing the precursor to enhance the magnetic and luminescent properties of crystalline MnWO4 based on these sintering temperature conditions. As the amount of rare earth ions was changed, the magnetic and luminescent characteristics were enhanced; however, after 0.1 mol.%, the luminescent characteristics decreased due to the concentration quenching phenomenon. In addition, a composite was prepared by mixing MnWO4 powder, with enhanced magnetism and luminescence properties due to the addition of dysprosium, with epoxy. To one of the two prepared composites a magnetic field was applied to induce alignment of the MnWO4 particles. Aligned particles showed stronger luminescence than the composite sample prepared with unsorted particles. As a result of this, it was suggested that it can be used as phosphor and a photosensitizer by utilizing the magnetic and luminescent properties of the synthesized MnWO4 powder with the addition of rare earth ions.

The influence of the electronic structure and concentration on the relative emission efficiency as well as the host lattice participation in the energy transfer processes are discussed.
