Color Point Tuning for (Sr,Ca,Ba) Si2O2N2:Eu2+ for White Light LEDs [PDF]
, 2009 Color point tuning is an important challenge for improving white light LEDs. In this paper, the possibilities of color tuning with the efficient LED phosphor Sr1−x−y−zCaxBaySi2O2N2:Euz2+ (0 ≤ x, y ≤ 1; 0.005 ≤ z ≤ 0.16) are investigated.

Electro-absorption of silicene and bilayer graphene quantum dots [PDF]
, 2016 We study numerically the optical properties of low-buckled silicene and AB-stacked bilayer graphene quantum dots subjected to an external electric field, which is normal to their surface.

More complete discussion of the time-dependence of the non-static line element for the universe [PDF]
, 1930 In a previous article,(1) I have shown that a continuous transformation of matter into radiation, occurring throughout the universe, as postulated by the astrophysicists, would necessitate a nonstatic line element for the universe, and have shown that ...

Spectral Shifts of Nonadiabatic High-Order Harmonic Generation
Applied Sciences, 2013 High-order harmonic generation (HHG) is a nonlinear nonperturbative process in ultrashort intense laser-matter interaction. It is the main source of coherent attosecond (1 as = 10−18 s) laser pulses to investigate ultrafast electron dynamics.
