Upgrading the Triboluminescence of ZnS:Mn Film by Optimization of Sputtering and Thermal Annealing Conditions

Abstract: A statistical method of the design of experiments and analysis of variance (ANOVA) was used to obtain optimized sputtering conditions for oriented ZnS thin films doped with 5% manganese on glass substrates. The effects on the five sputtering factors-substrate temperature, radio frequency power, sputtering pressure, sputtering time, and pre-sputtering time-were simultaneously investigated by using the design of experiments and ANOVA. Through only 16 experiments, it was proved statistically at the 5% level that … Show more

“…A way to remove all these states is a process known as a 'passivation' or 'capping', which consists of bonding of surface atoms to different materials (called passivating or capping agents) to prevent particle-particle interaction. Sol-gel synthesis, embedding the particles in a polymer matrix, electrodeposition, sonochemical synthesis, are certain synthesis routes which are used to obtain nanoparticles with a narrow size distribution [4][5][6][7][8][9]. In addition to this, the nanoparticles are also having high thermal stability, increased quantum efficiency for luminescence and radiative lifetime shortening with decreasing particle size [1].…”

“…[3] ZnS is an important semiconductor for a number of applications, including phosphors in cathode-ray tubes and flat-panel displays, [4] and thin-film electroluminescence. [5] It is a promising triboluminescence material, [6] especially for UV light-emitting diodes (LEDs) and laser diodes (LDs), because of the direct and wide bandgap of 3.77 eV (329.2 nm), and a relatively large exciton binding energy (~40 meV) for the hexagonal wurtzite phase at room temperature. [7] It is well known that rare-earth (RE) elements are effective luminescent centers for RE-doped semiconductors, because the excitation of the RE ions can occur by the recombination of photogenerated carriers confined in the semiconductor, and subsequent energy transfer to the RE ions.…”
