The dependence of luminescence intensity on  Sm3+^{3 + } ions concentration in alkali borotellurite (ABTe) glasses has  been studied. The quenching of luminescence intensity happens  around 0.75 mol% concentration of Sm3+^{3 + } ions and it... see more

In this work we present spectroscopic and photoluminescent properties of nanostructured polymeric composite films of nanocrystalline TiO2 and polyfuorenes (PF+nc-TiO2). The films were deposited onto glass and KBr substrates by spin-coating PF-in-toluene s... see more

The enhancement of light absorption and photoluminescence quenching properties of the bulk heterojunction systems which were fabricated using poly(N-vinylcarbazole) (PVK); poly(N-hexylthiophene)(P3HT) and fullerene derivative 1-(3-methoxycarbonyl) propyl-... see more

The luminescence properties of RAl3(BO3)4 (RAB, with R = Pr, Eu, Tb, Dy, Tm, Yb) huntite crystals grown from K2Mo3O10 flux were systematically characterized in order to investigate their excitation dynamics, with particular reference to the concentration ... see more

Transparent rare earth doped phosphate based glasses with and without silver nanoparticles (NPs) are obtained using conventional melt-quenching technique. In the present study, structural properties of glass are investigated by using X-ray Diffraction (XR... see more

Glass based on Nd3+-doped TeO2-PbO-Li2O has successfully been made by melt quenching technique and their thermal parameters have been determined using Differential Thermal Analyzer (DTA). The glass is then nucleated and/or growth by controlled heat treatm... see more

The paper is devoted to the changes in the X-ray luminescence spectra of nanoscale Y2O3 ceramics, namely the radiation associated with a self-trapped exciton. Additional heat treatment (annealing) of ceramic samples leads to changes in the exciton band of... see more

Disc brake is a disc in the braking system (brake system) which is located on the landing gear. During braking, friction occurs between the disc brake and brake lining, resulting in high heat and deformation resulting in decreased service life of the disc... see more

In this research the process of heating the steel material with a carbon content of 0.074 wt % to a temperature of 1000°C. The steel is subject to variations in holding time in the furnace for 10, 20, and 30 minutes. Then various steel that has been held ... see more
