Can a crystal types radio be made to work in infrared? With an antenna of lead sulfide or lead selenide perhaps?

An infrared crystal radio is a type of radio receiver that uses infrared light to detect and decode radio signals. It is a passive device that does not require external power to operate.
The radio consists of a crystal, typically made of semiconductor materials such as germanium or silicon, which acts as a detector of infrared light. When the crystal is exposed to infrared light, it produces a small voltage which is amplified and converted into an audible sound by a small speaker.
One of the main advantages of using an infrared crystal radio is that it does not require any external power source, making it a cost-effective and portable option. It also has a simple design and can be easily built by individuals with basic electronic knowledge.
An infrared crystal radio can receive a wide range of signals, including AM, FM, and shortwave radio. It can also pick up signals from other wireless devices such as cell phones and Wi-Fi networks.
To improve the reception of an infrared crystal radio, you can try using a longer antenna or a better quality crystal. You can also experiment with different placement and orientation of the radio and its components to find the best signal. Additionally, using a preamplifier or adding a tuning circuit can also enhance the reception of the radio.
