Descrição geral
Telluriumdioxide, also known as tellurium(IV) oxide, is a white powder with a melting point of 733 °C. TeO2 is characterized by its unique propertiesand is widely used in various applications, including optics, electronics, andas a precursor for the synthesis of tellurium-based materials. It is recognized for its strong optical characteristics and is employed in the production of optical fibers and other photonic devices. Additionally, it plays a crucial role in the preparation of diverse tellurium compounds for various chemical transformations. Our high-purity tellurium dioxide powder is distinguished by its low impurity levels, making it particularly suitable for sensitive electronic applications.[1][2][3]
Aplicação
Tellurium dioxide can be used:
- As a seed layer to fabricate hole-extracting electrodes in an organic photovoltaic device. The addition of TeO2 enhances the optical transmittance of the electrode.
- As a starting material to prepare tellurite glasses for gamma radiation shielding and other optical applications.

We report on spectroscopic properties and energy transfer of Tm(3+)/Ho(3+)-codoped tungsten tellurite glasses for 1.47microm amplifier. Fluorescence spectra and the analysis of energy transfer indicate that Ho(3+) is an excellent codopant for 1.47microm emission. Comparing with other tellurite glasses, the
