ZnS thin films are deposited on porous silicon (PS) substrates with different porosities by pulsed laser deposition (PLD). The photoluminescence (PL) spectra of the samples are measured at room temperature. The results show that the PL intensity of PS aft
Combing the time-correlated single photon counting (TCSPC) with fluorescence lifetime imaging microscopy (FLIM) provides promising opportunities in revealing important information on the microenvironment of cells and tissues, but the applications are thus
P_(2)O_(5).BaO.Na_(2)O.K_(2)O glasses doped with various content of Eu_(2)O_(3) were prepared using high temperature melting method, and the Eu^(2 ) ions in the phosphate glasses were obtained with the aid of the reductive action of silicon powder. The fa
A phase-diffractive optical element is designed to measure the topological charge of optical vortices. We use the scalar diffraction theory to calculate the far-field diffraction patterns. The simulation results show that almost all of the power of the in
