The effect of preliminary neutron irradiation on IR-LED characteristics during operation

Effects of Co-60 gamma radiation on the characteristics of red, green, and blue LEDs

“…These defects work as nonradiative centers. As a result, the non-radiative recombination centres dominate over the radiative ones This reduces the intensity output of an LED (2)(3)(4)(5)(6). Further, the gamma rays undergo Compton scattering inside the material of the LED.…”

“…Attempts are being made to develop radiation insensitive LEDs (4). This necessitates investigations on the durability, reliability of LEDs under low, medium, and harsh radiation environments (4)(5)(6). The radiation induced modifications in the performance of LEDs must be within specified limits (1).…”

“…Effects of verity of radiations including gamma rays, electrons, neutrons, and protons are reported in the literature (1)(2)(3)(4)(5)(6)(7)(8). However, we see no report displaying the effects of gamma radiation particularly on I-V and Intensity-Power characteristics of RGB LEDs in the dose range 1.8 kGy to 172.8 kGy.…”
