“…A minimum current 2 mA and above is the basic requirement for higher emission rate. In general, the TiO 2 has the lowest emission rate with ×10 13 per second [7] as compared to other materials the average emission rate can be up to ×10 15~1 0 27 per second but depends on optimal condition. Improper applied the voltage to material is caused the back current effect which leads the imperfection emission rate is generated and contribute a side effect on the light extraction process ,an example is shown in Figure 4.…”

Signal characteristics by optimization the output coupling ratio of multi-wavelength Brillouin fiber laser incorporating fiber Bragg grating in a ring cavity technique AIP Conference Proceedings 1835, 020002 (2017) Abstract.The optimal input voltage and spontaneous emission rate characteristics based on different material of a LED chip which is Gallium Nitride, Indium Nitride, Zinc Oxide, Zinc Selenide and Titanium Dioxide are simulated and successfully analyzed. These materials have been chosen as selected material due to highly potential being used in the next generation LED. To obtain a good emission state, the optimal voltage for Gallium Nitride, Zinc Oxide and Titanium Dioxide are fall in the range of 2.6V to 3V. Meanwhile, Indium Nitride and Zinc Selenide are produce lower optimal voltage in between 1.2V to 1.6V. Gallium Nitride and Indium Nitride has the ability to achieve a higher emission rate as only required the minimum current below than 0.05 mA as compared to other materials. Furthermore, the Titanium Dioxide has the lowest emission rate with ×1013 per second as compared to other materials the average emission rate can be up to ×1015~1027 per second.
