Abstract:
Проведено модифiкацiю рiдинного спектрофлуорофотометра з метою використання його для дослiдження твердотiльних зразкiв. Виявлено можливi артефакти, якi з’являються в спектрах за рахунок
розсiяння збуджуючого свiтла на шорстких та вiдбиваючих поверхнях твердих тiл. Проведено систематизацiю артефактiв.
Description:
Spectrofluorometer for studying liquids and solutions was modified in order to extend its applicability and to
enable measurements of solid samples. Two types of holders for solid samples were fabricated. This provided
an opportunity to explore samples of various sizes and configurations. Design of these new details of the
instrument ensures the rotation of the sample, so that the measurements can be done at different incident angles
of the excitation light. Several artifacts that emerge in the spectra due to the exciting light scattering on rough
and reflecting surfaces of solids were revealed and thoroughly analyzed. As a result of the detailed studies of
these undesirable spectral features, which can be encountered in different spectral ranges, all artifacts were
systematized in the comprehensive table.
