Room temperature phosphorescence quenching study of coumarins. Indirect determination of warfarin in pharmaceuticals
(Royal Society of Chemistry, 2014-03)
Room temperature phosphorescence of the 1-bromonaphthalene/b-cyclodextrin/cyclohexane inclusioncomplex was studied in the presence of coumarins: warfarin, coumarin, dicumarol and umbelliferone.The differences encountered ...
Mn-doped ZnS phosphorescent quantum dots: Coumarins optical sensors
(Elsevier Science Sa, 2017-01)
Mn-doped ZnS quantum dots (QDs) have increasingly attracted much attention as luminescent sensors. Mn+2doping promotes a strong phosphorescence-like emission, allowing the development of novel and highly selective sensing ...
Flow injection analysis with on-line nylon powder extraction for room-temperature phosphorescence determination of thiabendazole
(Elsevier Science, 2009-07)
A fast and very selective flow-through phosphorescence optosensor was designed and characterized for the determination of the fungicide thiabendazole in water samples. For the first time, thiabendazole was determined using ...
Room temperature phosphorescence of the 1-bromonaphthalene/b-cyclodextrin inclusion complex: comparison between right-angle and front-face illumination geometry
(Royal Society of Chemistry, 2013-10)
The importance of correction for inner filter effects has been demonstrated in the case of the widely studied 1-bromonaphthalene/ b-cyclodextrin inclusion complex by means of right-angle and front-face illumination geometry.
Luminiscent properties of benzqxazolinones
(1986)
The UV absorption and fluorescence soectral bands of 2-benzoxazolinone and 6-methoxy-2-benzoxazolinone have been recorded in solution at room temperature. The phosphorescence spectral bands, their Quantum yields and mean ...
Phloxine B as a probe for entrapment in microcrystalline cellulose
(Molecular Diversity Preservation International, 2012-02)
The photophysical behaviour of phloxine B adsorbed onto microcrystalline cellulose was evaluated by reflectance spectroscopy and laser induced time-resolved luminescence in the picosecond-nanosecond and microsecond- ...

In this M.Sc. in Physics is presented the experimental results of our study of the optical properties of dropcast films containing a set of few domains of organic interacting derivative molecules of Phenazine, which were ...
Optimização de blendas de matrizes orgânicas condutoras inertes opticamente e moléculas de fenazina para fabricação de camada ativa em dispositivos eletro-ópticos fosforescentes
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2021-07-15)
In the present work, the optical properties of phenazine-based 1,2,3-triazole thin films
dispersed in mCP (1,3-Bis (N-carbazolyl) benzene), an optically inert matrix and electric
current conductor, were studied. The ...
