LED colors

One of the major characteristics of an LED uses a different color. Initially what is full form of LED colors were restricted only red LEDs were available. But after semiconductor processes were improved and new research was undertaken to investigate in direction of new LEDs many different colors were available. 

Different types of LED colors with wavelength given below :

1. Infrared 
Wavelength - > 760
Voltage drop -  < 1.9
Semiconductor material - Gallium arsenide, Aluminium gallium arsenide

2.  Red
Wavelength - 610-760
Voltage drop - 1.6 TO 2.0
Semiconductor material - Galium arsenide phosphide, Aluminium gallium arsenide

3. Violet
Wavelength - 400-450
