From: Highly Responsive Ultraviolet Sensor Based on ZnS Quantum Dot Solid with Enhanced Photocurrent
Reaction Time | Lifetime [τ1] | Lifetime [τ2] | Avg. Lifetime [τ] |
|---|---|---|---|
ZnS 12 hrs | τ1 = 3.004 × 10−10s (A1 = 46.72) | τ2 = 6.44 × 10−8s (A2 = 53.28) | τ = 64 × 10−9s |
ZnS 24 hrs | τ1 = 1.4355 × 10−10s (A1 = 90.70) | τ2 = 5.730 × 10−9s (A2 = 9.30) | τ = 4.636 × 10−9s |
ZnS 36 hrs | τ1 = 1.386 × 10−10s (A1 = 87.92) | τ2 = 5.9980 × 10−9s (A2 = 12.08) | τ = 5.15 × 10−9s |
ZnS 48 hrs | τ1 = 1.4739 × 10−10s (A1 = 83.81) | τ2 = 5.2789 × 10−9s (A2 = 16.19) | τ = 4.63 × 10−9s |
