I'm guessing you meant to ask why aren't UV rays used for transmitting instead of IR.
UV is higher energy than visible spectrum, while IR is lower. UV can potentially damage the eye if stared into at close range (kids). UV takes more power to drive. UV LEDs are only recently available (5 yrs or so), much more expensive than IR, and there are no cheap UV receivers.
