I was doing some experiment recently and got stuck with this problem here:
Is it possible to make a semi-transparent/translucent emitter? Something like 'Minority Report' screen, if you know what I mean.

I'm not sure what you mean by the 'Minority Report' screen, but try this:

1. create a new material
2. add an emitter
3. set Watts=10.0

4. add a BSDF
5. set Nd=1.0
6. set Transmittance to 255,255,255

7. add another BSDF
8. set ND=1.5
9. set Roughness=0.0

I'm testing here using the stage1_tom preview scene. You will probably have to adjust the power of the emitter (or make it an mxi emitter) and the roughness/nd of the second BSDF to get it to look how you want to in another scene.

Man, I found the problem: I forgot to set Transmittance to 255,255,255 (working/studying over 24 hours is killing me).
Thanks for help, JDHill

BTW, here's a couple of shots from 'Minority Report'
