abstract = "Luminescentne pojave se neizbežno javljaju u mnogim oblastima, od svakodnevnog života do sofisticiranih aplikacija u nauci i tehnici. Odavno su predmet istraživanja, gde se modeluju procesi i realizuju praktični sistemi.
Nauka o materijalima je vezana, kako za sve veći broj novih materijala, tako i za veliki broj materijala sa dugom istorijom. Sa druge strane postoji više procesa koji dovode do pojave luminescencije. Zato je oblast luminescencije multidisciplinarna, stalno prisutna u kombinaciji sa mnogim naučnim disciplinama.
U ovom radu su razmatrani novi materijali, razvijeni na različite načine. Neki od njih su sintetizovani od češće prisutnih hemijskih jedinjenja, a neki su vezani za razne matrice i
primese retkih zemalja, čime su, prema današnjem trendu, vezani za kvantne generatore – lasere, kao i različite tipove senzora, detektora i sl. Promene koncentracije primesa za koje
su aktivni materijali kod kvantnih generatora vezani, direktno su dovele do promene koeficijenta korisnog dejstva. To se postiže izlaganjem aktivnih materijala snopovima elektromagnetnog zračenja, kao i izlaganjem nuklearnim i drugim vrstama zračenja.
Praćene su luminescentne pojave iz literature, a za izabrane grupe materijala koje su proizvod laboratorija, na aparaturama / sistemima, gde je temperatura bila parametar, a laserski izvor u okviru spektrofluorometarskih sistema, izvršena je serija merenja predstavljena u ovom radu. Iz
dobijenih spektara interpretirani su razni podaci o materijalu. U ovom radu su predstavljena karakteristična vremena, vezana za oblike izmerenih spektara u vremenskom domenu., Luminescent phenomena inevitably occur in many areas, from
everyday life to sophisticated applications in science and
technique. They have long been the subject of research, where
processes are modeled and practical systems are realized.
Materials science is related to both an increasing number of new
materials and a large number of materials with a long history. On
the other hand, there are several processes that lead to the
appearance of luminescence. That is why the field of luminescence
is multidisciplinary, constantly present in combination with many
scientific disciplines.
In this work, new materials, developed in different ways, were
considered. Some of them are synthesized from more commonly
present chemical compounds, and some are related to various
matrices and admixtures of rare earths, which, according to today's
trend, are related to quantum generators - lasers, as well as various
types of sensors, detectors, etc. Changes in the concentration of
admixtures, to which the active materials in quantum generators
are connected, directly led to a change in the useful effect
coefficient. This is achieved by exposing active materials to beams
of electromagnetic radiation, as well as by exposing them to
nuclear and other types of radiation.
Luminescent phenomena from the literature were monitored,
and for selected groups of materials that are the product of the
laboratory, on apparatus / systems, where temperature was a
parameter, and the laser source within spectrofluorometric systems,
a series of measurements presented in this paper was performed.
Various data about the material were interpreted from the obtained
spectra. This paper presents characteristic times related to the
shapes of the measured spectra in the time domain.",
