| Description | Journal: Japanese Journal of Applied Physics The emissive properties of $Al_{2}O_{3}/Er_{3}Al_{5}O_{12}$ eutectic composite were measured in the temperature range of 1000 to 1700 K. It was confirmed that the $Al_{2}O_{3}/Er_{3}Al_{5}O_{12}$ eutectic composite has selective emission bands at a wavelength of 1.5 µm attributable to $Er^{3+}$ ions. It is found that the intensity obeys the T$ ^{4}$-law. The emittance of over 0.8 is observed in the selective region. Since these emission bands match up the sensitive region of the GaSb PV cell spectrally, the $Al_{2}O_{3}/Er_{3}Al_{5}O_{12}$ eutectic composite is a suitable emitter material for using in thermophotovoltaic generation systems. The effects of temperature and thickness on the selective emission efficiency have been studied and discussed. |
