Orange emission in Pr3+-doped fluoroindate glasses
(2013-01-01)
We synthesize and study the properties of praseodymium doped fluoroindate glasses. Glass compositions with praseodymium molar concentrations up to 5% were obtained with good optical quality. Thermal, optical, and luminescence ...

Relação entre uniformidade da produtividade e indicadores de uniformidade da irrigação em sistema de irrigação por microaspersão em citros
(2017-01-01)
One of the recommended design criteria for localized irrigation systems is based on the desired emission uniformity, assuming that the uniform water application generates uniform production. The aim of this study was to ...
Broad combined orange-red emissions from Eu2+- and Eu3+-doped low-silica calcium aluminosilicate glass
(OPTICAL SOC AMERWASHINGTON, 2012)
In this paper, a broad combined orange-red emission from Eu2+- and Eu3+-doped low-silica calcium aluminosilicate (LSCAS) glass is reported. Spectroscopic results demonstrate that it is possible to tune the emission wavelength ...
SOIL CO2 EMISSION ASSOCIATED WITH LIMING IN AREA OF CONVERSION OF ORANGE FOR SUGAR CANE
(Soc Brasil Engenharia Agricola, 2014-09-01)
The soil CO2 emission (FO2) in agricultural areas is resulting from the interaction of several factors, as amended by the practice of soil management practices and crop, in addition to the local edaphoclimatic conditions. ...
Amorphous manganese polyphosphates: preparation, characterization and incorporation of azo dyes
(Springer, 2009-05-01)
Amorphous Mn(2+) polyphosphate materials were prepared at room temperature through the coacervation of polyphosphate solutions. These new materials display the typical Mn(2+) red emission with a broad band centered at ...

Growth mechanism and vibrational and optical propeties of SrMoO4: Tb3+, Sm3+ particles: green-orange tunable color
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Materiais, 2020-12-10)
A SrMoO4 series co-doped with Tb3+ and Sm3+ was successfully prepared by the sonochemical method. The particles were characterized by X-ray diffraction, Raman spectroscopy, field emission gun scanning electron microscopy, ...
Green-to-red light tuning by up-conversion emission via energy transfer in Er3+-Tm3+-codoped germanium-tellurite glasses
(Elsevier BVAmsterdam, 2014-06)
The luminescence properties through up-conversion emission process of Er3+-Tm3+-codoped germanium- tellurite glasses was carefully investigated by using UV-visible-near-infrared absorption spectroscopy, emission spectroscopy ...
