Photoluminescence characterization and heat treatment effect on luminescence behavior of BaTa2O6:Dy3+ phosphor

“…Therefore, most rare‐earth elements are generally preferred for phosphor and laser materials production as dopants. Potential application fields of rare earth‐doped phosphor materials include solar panels, field‐emission displays (FEDs), scintillation, cathode‐ray tubes (CRTs), vacuum fluorescent displays (VFDs) and white light‐emitting diodes (W‐LEDs) . White LEDs are generally considered to be the new generation light sources, which are able to replace the fluorescent lamps, because of their excellent features in terms of low energy consumption, fast response, mercury free, high efficiency, low voltage adjustability, environmental‐friendly and energy‐saving devices.…”

Synthesis and photoluminescence properties of Dy3+ doped white light emitting CdTa2O6 phosphors

“…This interesting behaviour can be atributed to the crystal structure. In a study by Marciniak et al [45] for the cubic system, the CTB intensity is strongly quenched with increasing concentration whereas for monoclinic lattice it remains practically unchanged. Similarly, it was seen that the increasing dopant concentration changed charge transfer band intensities significantly for orthorhombic columbite system.…”

Synthesis, Structural Properties and Visible–Near Infrared Photoluminescence of Trivalent Erbium (Er3+) Doped BaTa2O6 Phosphor

“…Son otuz yıldır uygulama alanlarının artması ile hızlı gelişim gösteren üç değerlikli nadir toprak iyonu (NT +3 ) katkılı lüminesans malzemelerin üretimi ve uygulamaları bir hayli önem kazanmakta ve yapılan çalışmalar yakından takip edilmektedir [1][2][3]. NT +3 iyon katkılı lüminesans malzemeler veya fosforlar mükemmel ışıma özelliği, yüksek homojenliğe sahip olma, düşük termal iletkenlik, uzun kullanım ömrü, enerji tasarrufu ve düşük güç tüketimi nedeniyle önemli kullanım alanına sahiptirler.…”
