Opis:: Novel inorganic luminescent materials have provided improvements in lighting, display, and optical devices. They are generally used for decorative applications, safety signs, and tolls. The characteristics of the photoluminescent pigments depend on both physical and chemical characteristics. In this study, particle size distribution effects on the after-glow time of the bluish-green and yellowish-green pigments were investigated. Milling times of the pigments were chosen as 30 min, 60 min and 90 min and they were applied on the wall tile surfaces with a constant ratio. Depending on the milling time, after-glow property of the pigments were compared by using photometer equipment. Correlations between pigments particle size distribution and after-glow time of the pigments were also discussed in this presentation.

Opis:: One of the persistent luminescence materials and providing emission in blue-green areas emission bands for typical phosphors ($SrAl_2O_4$:$Eu^{2+}$, $CaAl_2O_4$:$Eu^{2+}$, $MgAl_2O_4$:$Eu^{2+}$) are generally focused on recently. These systems are reliable, stable, not containing radiation and they have long term photoluminescence emission. These systems are mainly used in a wide range of products such as building, ceramics, line marks for highways, tolls, etc. In this study, $SrAl_2O_4$:$Eu^{2+}$ phosphorescent pigment was used on wall tile surfaces. Due to the high firing temperature after-glow property of the pigment decreases. To increase afterglow property frit compositions with low temperature melting point were developed and depend on the composition, after-glow properties of the tiles were measured by photometer.

Opis:: Thermoluminescence properties of TlGaSeS layered single crystals were investigated in the temperature range of 280-720 K. Thermoluminescence glow curve exhibited three peaks with maximum temperatures of ≈370, 437, and 490 K. Curve fitting, initial rise and peak shape methods were used to determine the activation energies of the trapping centers. All applied methods resulted with energies around 0.82, 0.91, and 0.99 eV. Dose dependence of the thermoluminescence intensity was also examined for the doses in the range of 0.7-457.6 Gy. Peak maximum intensity of the observed peak around 370 K showed an increase up to a certain dose and then a decrease at higher doses. This non-monotonic dose dependence was discussed under the light of a reported model in which different kinds of competition between radiative and nonradiative recombination centers during excitation or heating stages of the thermoluminescence process are explained.

Opis:: This work is concerned with a study on the operating characteristics of a self-axial extraction-type glow-discharge ion source. This compact ion source, with conical anode of various divergence angle Θ, can work under different operating conditions. An output ion beam currents I_{b} were measured at a distance d_{cc} = 5 cm from the plane cathode, and were found to be dependent upon the gas pressure p, angle Θ and the discharge current I_{d}. High ion beam currents of 85 μA and 410 μA were obtained at the optimum angle Θ=30° for discharges: [N₂ gas, p = 2.9×10¯² mbar, I_{d} = 2 mA] and [H₂ gas, p = 7.7×10¯² mbar, I_{d} = 2 mA], respectively.
