essential need to develop device technology toward enhanced NIR light harvesting. In this
study, we have documented the design of an indigenously developed time correlated single
photoncounting (TCSPC) system working in the NIR (900 nm–1700 nm) spectral region. The
system is compatible to study transient photoluminescence of device samples under tunable
bias voltages. The liquid nitrogen cooling and electrical heating of the sample chamber …
