Surface plasmon enhanced spontaneous emission rate of InGaN/GaN quantum wells probed by time-resolved photoluminescence spectroscopy (2005)

Okamoto, Koichi, Niki, Isamu, Scherer, Axel, Narukawa, Yukio, Mukai, Takashi, Kawakami, Yoichi

We observed a 32-fold increase in the spontaneous emission rate of InGaN/GaN quantum well (QW) at 440 nm by employing surface plasmons (SPs) probed by time-resolved photoluminescence spectroscopy. We...

A Methodological Study of the Best Solution for Generating White Light Using Nitride-Based Light-Emitting Diodes (2005)

YAMADA, Motokazu, NARUKAWA, Yukio, TAMAKI, Hiroto, MURAZAKI, Yoshinori, MUKAI, Takashi

In search of suitable white-LED for general illumination, we fabricated various types of white-LEDs using different methods. As the first method, we used the multichip method in which multiple...
