Abstract
Low toxic q
uantum dot light
-
emitting diodes (QD
-
LEDs)
were fabricated
using ZnS
-
AgInS
2
solid solution
(ZAIS)
and their
electrolumine
scent properties were investigated.
The emission color of ZAIS c
ould
be controlled by changing fraction of ZnS content in
ZAIS.
Th
e QD
-
LED using
the
ZAIS
,
which
gave
86% of
the photoluminescence quantum yield
,
exhibited
red light emission from ZAIS i
n
the DC voltage and
its
external quantum efficiency
was
1.9%
