Energy densities of 310 nm and 265 nm by irradiation with ultraviolet light-emitting-diode device. Power fluencies of tested devices were calculated by the following formula: Energy density (mJ/cm2) = Power density (mW/cm2) × Time (seconds)
| Time (sec) | 10 | 30 | 60 | 120 | 180 | 240 |
|---|---|---|---|---|---|---|
| 310 nm | 17.5 | 52.5 | 105 | 210 | 315 | 420 |
| 265 nm | 17.1 | 51.3 | 102.6 | 205.2 | 307.8 | 410.8 |
Energy density (mJ/cm2)
