Transparent Er3+-activated lead fluorogermanate glass ceramics
(2003-12-01)
Transparent glass ceramics containing β-PbF2:Er 3+ nanocrystals were obtained through appropriate thermal treatments of a glass of molar composition 60PbGeO3-10PbF2-30CdF 2 doped with 0.5 mol% Er3+. Their optical properties, ...

Avaliação do emprego de lodo de tratamento de esgoto (LTE) e casca de arroz (CA) na produção de cerâmicas vermelhas
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2022-08-02)
Rice husk (RH) and sewage sludge (SS) are industrial by-products largely produced daily. The SS is classified as class II-A (not inert) non-hazardous waste. Despite its physical and chemical similarities to the ceramics ...
Er3+-doped niobium alkali germanate glasses and glass-ceramics: NIR and visible luminescence properties
(Elsevier B.V., 2019-10-01)
Niobium alkali germanate glasses doped with Er3+ up to 4.0 mol% were synthesized by the melt-quenching technique. Glass-ceramics were obtained by controlled heat treatment of the pristine glass. Thermal and optical properties ...
Archaeometric analysis of ceramic production in Tiwanaku state (c.500-1000ce): An exploratory study
(Wiley, 2020)
The chemical and mineralogical characterization of seven ceramic fragments produced within Tiwanaku state (c.500-1000 ce) is reported. The instrumental techniques used included X-ray elemental and mineralogical chemical ...
