Eu3+ and Sm3+ co-doped molybdate phosphors have been synthesized via hydrothermal method. The phosphors have the advantages of narrower particle size distribution and regular homogeneous shape. The luminescent properties of the molybdate phosphors were systematically studied. The introduction of Sm3+ into the red-emitting phosphors can generate a strong excitation line at 405 nm, originating from...
A capillary discharge 46.9 nm Ne-like Ar laser is achieved with peak current of 20–23 kA. The variation of laser pulse duration with initial Ar pressure and rise-time of main current is reported. Measurements show that the laser pulse durations slightly increase with the increased pressure and increased rise-time of current. A comparison of the experimental results with the calculation of snow-plow...
