To produce natural and vivid color, the color rendering index of white light-emitting diodes (WLEDs) with single phosphors is usually lower than 70, which is problematic for LED applications. A commonly used method to resolve this issue is to enhance

In this study, the effects of bismuth additives are investigated based on the dielectric properties by the empirical law and the order–disorder model for the Pb(Fe2/3W1/3)0.7Ti0.3O3–x wt.% Bi2O3 ceramics. The grain size initially increased and th

Phosphor-converted white light-emitting diodes (pc-WLEDs) were fabricated using low-melting-temperature TeO 2 -based glass powders, which are a potential packaging material. The novel glass component, TeO 2 -B 2 O 3 -ZnO-Na 2 O doped with WO 3 , show

This paper proposes a new estimation for the eddy-current loss of MnZn ferrite cores. The eddy-current loss plays a critical role in the frequency range of 100-500 kHz, whereas the amount of the hysteresis loss dominates the core loss of magnetic dev

The empirical law, ɛ = ɛ m /[1 + ( T − T m ) γ /2 σ 2 ] or ɛ = ɛ m /{1+[( T − T m )/ Δ ] ξ }, are usually used to estimate the degree of the diffused phase transition of the ferroelectric relaxors. As the values of γ or σ ( ξ or Δ ) a
