## CPC

- G01J 1/429: {applied to measurement of ultraviolet light (using counting tubes G01T)}
- G01J 1/02: Details
- G01J: MEASUREMENT OF INTENSITY, VELOCITY, SPECTRAL CONTENT, POLARISATION, PHASE OR PULSE CHARACTERISTICS OF INFRARED, VISIBLE OR ULTRAVIOLET LIGHT; COLORIMETRY; RADIATION PYROMETRY (light sources F21, H01J, H01K, H05B; investigating properties of materials by optical means G01N)

## Abstract

In accordance with at least one aspect of this disclosure, an ultraviolet radiation (UV) sensor includes a UV sensitive material and a first electrode and a second electrode connected in series through the UV sensitive material such that UV radiation can reach the UV sensitive material. The UV sensitive material can include at least one of zinc tin oxide, magnesium oxide, magnesium zinc oxide, or zinc oxide. The electrodes can be interdigitated comb electrodes.

## Claims

### Claim 1

A method for manufacturing a radiation sensor, comprising:
depositing or printing a radiation sensitive material on or within a plurality of electrodes, wherein the electrodes are interdigitated and the radiation sensitive material is deposited or printed in a space between a plurality of electrode extensions, wherein depositing or printing the radiation sensitive material includes forming the radiation sensitive material to be coplanar with the electrodes to form a sensor layer.

### Claim 2 (depends on 1)

The method of claim 1, further comprising depositing or printing the electrodes.

### Claim 3 (depends on 1)

The method of claim 1, further comprising forming a plurality of the sensor layers one on top of another such that each sensor layer is electrically separated by the radiation sensitive material but radiation is allowed to pass through each layer to reach the radiation sensitive material in each sensor layer.
