Light emitting transistors on chip to reduce heat

Could the same principle of LEDs be applied to chip (silicon or gallium) design to shift the infra-red heat towards the blue range then direct it away fromt the chip with fiber to allow the chip to remain cooler? This would change the wavelength of…
