Analysis of Er3+ incorporation in SnO2 by optical investigation
(Sociedade Brasileira de Física, 2006-06-01)
Er3+ emission in the wide bandgap matrix SnO2 is observed either through a direct Er ion excitation process as well as by an indirect process, through energy transfer in samples codoped with Yb3+ ions. Electron-hole ...

Hierarchy of factors driving N2O emissions in non‐tilled soils under different crops
(Wiley, 2013-10)
Nitrous oxide (N2O) is emitted to the atmosphere as a by‐product of nitrification and denitrification by soil microbial processes. Differences in climate, soil and management regulate these processes, causing N2O emissions ...
Infrared cascade and cooperative multicolor upconversion emissions in Y8V2O17:Eu:Yb nanophosphors
(Optical Society of America - OSAWashington, DC, 2013-02)
This work reports on the efficient cooperative upconversion and infrared cascade downconversion emissions in a novel Y8V2O17:Eu:Yb nanophosphor. The excitation with UV light produces emission in the 950- 1000 nm region, ...
Greenhouse gas emissions and N2o mitigation in beef cattle production on tropical pasture
(Universidade Estadual Paulista (Unesp), 2016-02-03)
Metano (CH4) e óxido nitroso (N2O) são dois dos mais importantes gases de efeito estufa emitidos pela pecuária. Eles são produzidos pelas excretas dos animais e fertilizantes. No Brasil, a quantidade emitida destes gases ...

Connecting morphology and photoluminescence emissions in β-Ag2MoO4 microcrystals
(2022-02-01)
This work elucidates the morphology-photoluminescence (PL) emission relationships, based on experimental and calculated results, on β-Ag2MoO4 samples synthesized by microwave-assisted hydrothermal method. It was shown that ...
